The organization infection fatality ratio associated with N-H…D(only pair) hydrogen bonds in between a pair of adjoining copy enables the enhancement of the increase line since the principal architectural design. The right providing elements within the a couple of polymorphs couldn’t end up being identified with no calculations with the pairwise interaction powers. Your triclinic construction includes a higher Medicine history denseness as well as a decrease (by 2.60 kcal mol-1) lattice electricity as outlined by routine information in comparison to the orthorhombic structure. This permits people in order to believe how the triclinic kind of 3-cyclopropyl-5-(2-hydrazinylpyridin-3-yl)-1,Two,4-oxadiazole is the a lot more stable.The intramolecularly matched up homoleptic diorgano selenide bis2,6-bis[(dimethylamino)methyl]phenyl selenide, C24H38N4Se or even R2Se, wherever Third will be 2,6-(Me2NCH2)2C6H3, 18, was created and it is ligation tendencies together with PdII and HgII precursors had been explored. The reaction involving 18 with SO2Cl2 as well as K2PdCl4 ended in the development from the meta C-H-activated dipalladated complex μ-2,2′-bis[(dimethylamino)methyl]-4,4′-bis[(dimethylazaniumyl)methyl]-3,3′-selanediyldiphenyl-κ4C1,N2C1′,N2′bis[dichloridopalladium(The second)], [Pd2Cl4(C24H38N4Se)] as well as [R(H)PdCl22Se], 15. On the other hand, whenever ligand 18 has been responded with HgCl2, the reaction available any dimercurated selenolate complicated, μ-bis2,6-bis[(dimethylamino)methyl]benzeneselanolato-κ4N2,SeSe,N6-μ-chlorido-bis[chloridomercury(II)], [Hg2(C12H19N2Se)Cl3] or RSeHg2Cl3, 16, where two HgII ions are bridged by selenolate and chloride ligands. In palladium complex 15, there are two molecules located on crystallographic twofold axes and within each molecule the Pd moieties are related by symmetry, but there are still two independent Pd centers. Mercury complex 16 results from the cleavage of one of the Se-C bonds to form a bifurcated SeHg2 moiety with the formal charge on the Se atom being -1. In addition, one of the Cl ligands bridges the two Hg atoms and there are two terminal Hg-Cl bonds. Each Hg atom is in a distorted environment which can be best described as a T-shaped base with the bridging Cl atom in an apical position, with several angles close to 90° and with one angle much larger and closer to 180°.Bis(5-amino-1,2,4-triazol-4-ium-3-yl)methane dichloride (BATZM·Cl2 or C5H10N82+·2Cl-) was synthesized and crystallized, and the crystal structure was characterized by single-crystal X-ray diffraction; it belongs to the space group C2/c (monoclinic) with Z = 4. The structure of BATZM·Cl2 can be described as a V-shaped molecule with reasonable chemical geometry and no disorder, and its one-dimensional structure can be described as a rhombic helix. The specific molar heat capacity (Cp,m) of BATZM·Cl2 was determined using the continuous Cp mode of a microcalorimeter and theoretical calculations, and the Cp,m value is 276.18 J K-1 mol-1 at 298.15 K. The relative deviations between the theoretical and experimental values of Cp,m, HT – H298.15K and ST – S298.15K of BATZM·Cl2 are almost equivalent at each temperature. The detonation velocity (D) and detonation pressure (P) of BATZM·Cl2 were estimated using the nitrogen equivalent equation according to the experimental density; BATZM·Cl2 has a higher detonation velocity (7143.60 ± 3.66 m s-1) and detonation pressure (21.49 ± 0.03 GPa) than TNT. The above results for BATZM·Cl2 are compared with those of bis(5-amino-1,2,4-triazol-3-yl)methane (BATZM) and the effect of salt formation on them is discussed.The title compound, 10-iodo-1,2-dihydroisoquinolino[2,1-b][1,2,4]benzothiadiazine 12,12-dioxide, C15H11IN2O2S (8), was synthesized via the metal-free intramolecular N-iodosuccinimide (NIS)-mediated radical oxidative sp3-C-H aminative cyclization of 2-(2′-aminobenzenesulfonyl)-1,3,4-trihydroisoquinoline, C15H16N2O2S (7). The amino adduct 7 was prepared via a two-step reaction, starting from the condensation of 2-nitrobenzenesulfonyl chloride (4) with 1,2,3,4-tetrahydroisoquinoline (5), to afford 2-(2′-nitrobenzenesulfonyl)-1,3,4-trihydroisoquinoline, C15H14N2O4S (6), in 82% yield. The catalytic hydrogenation of 6 with hydrogen gas, in the presence of 10% palladium-on-charcoal catalyst, furnished 7. Products 6-8 were characterized by their melting points, IR and NMR (1H and 13C) spectroscopy, and single-crystal X-ray diffraction. The three compounds crystallized in the monoclinic space group, with 7 exhibiting classical intramolecular hydrogen bonds of 2.16 and 2.26 Å. All three crystal structures exhibit centrosymmetric pairs of intermolecular C-H…π(ring) and/or π-π stacking interactions. The docking studies of molecules 6, 7 and 8 with deoxyribonucleic acid (PDB id 1ZEW) revealed minor-groove binding behaviours without intercalation, with 7 presenting the most favourable global energy of the three molecules. Nonetheless, molecule 8 interacted strongly with the DNA macromolecule, with an attractive van der Waals energy of -15.53 kcal mol-1.The crystal structures of four new chiral [1,2,3]triazolo[5,1-b][1,3,4]thiadiazines are described, namely, ethyl 5′-benzoyl-5′H,7′H-spiro[cyclohexane-1,6'-[1,2,3]triazolo[5,1-b][1,3,4]thiadiazine]-3′-carboxylate, C19H22N4O3S, ethyl 5′-(4-methoxybenzoyl)-5′H,7′H-spiro[cyclohexane-1,6'-[1,2,3]triazolo[5,1-b][1,3,4]thiadiazine]-3′-carboxylate, C20H24N4O4S, ethyl 6,6-dimethyl-5-(4-methylbenzoyl)-6,7-dihydro-5H-[1,2,3]triazolo[5,1-b][1,3,4]thiadiazine-3-carboxylate, C17H20N4O3S, and ethyl 5-benzoyl-6-(4-methoxyphenyl)-6,7-dihydro-5H-[1,2,3]triazolo[5,1-b][1,3,4]thiadiazine-3-carboxylate, C21H20N4O4S. The crystallographic data and cell activities of these four compounds and of the structures of three previously reported similar compounds, namely, ethyl 5′-(4-methylbenzoyl)-5′H,7′H-spiro[cyclopentane-1,6'-[1,2,3]triazolo[5,1-b][1,3,4]thiadiazine]-3′-carboxylate, C19H22N4O3S, ethyl 5′-(4-methoxybenzoyl)-5′H,7′H-spiro[cyclopentane-1,6'-[1,2,3]triazolo[5,1-b][1,3,4]thiadiazine]-3′-carboxylate, C19H22N4O4S, and ethyl 6-tions. Molecular mechanics methods (force field OPLS3e) and the DFT B3LYP/6-31G+(d,p) method show that the compound forming enantiomeric pairs via weak N-H…N hydrogen bonds is subject to greater distortion of the geometry under the influence of the intermolecular interactions in the crystal. For intramolecular N-H…O and S…O interactions, an analysis of the noncovalent interactions (NCIs) was carried out. The cellular activities of the compounds were tested by evaluating their antiproliferative effect against two normal human cell lines and two cancer cell lines in terms of half-maximum inhibitory concentration (IC50). Some derivatives have been found to be very effective in inhibiting the growth of Hela cells at nanomolar and submicromolar concentrations with minimal cytotoxicity in relation to normal cells.Methyl 4-(4-fluorophenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate, (I), was found to exhibit solvatomorphism. The compound was prepared using a classic Biginelli reaction under mild conditions, without using catalysts and in a solvent-free environment. Single crystals of two solvatomorphs and one anhydrous form of (I) were obtained through various crystallization methods. The anhydrous form, C13H13FN2O3, was found to crystallize in the monoclinic space group C2/c. It showed one molecule in the asymmetric unit. The solvatomorph with included carbon tetrachloride, C13H13FN2O3·0.25CCl4, was found to crystallize in the monoclinic space group P2/n. The asymmetric unit revealed two molecules of (I) and one disordered carbon tetrachloride solvent molecule that lies on a twofold axis. A solvatomorph including ethyl acetate, C13H13FN2O3·0.5C4H8O2, was found to crystallize in the triclinic space group P-1 with one molecule of (I) and one solvent molecule on an inversion centre in the asymmetric unit. The solvent molecules in the solvatomorphs were found to be disordered, with a unique case of crystallographically induced disorder in (I) crystallized with ethyl acetate. Hydrogen-bonding interactions, for example, N-H…O=C, C-H…O=C, C-H…F and C-H…π, contribute to the crystal packing with the formation of a characteristic dimer through N-H…O=C interactions in all three forms. The solvatomorphs display additional interactions, such as C-F…N and C-Cl…π, which are responsible for their molecular arrangement. The thermal properties of the forms were analysed through differential scanning calorimetry (DSC), hot stage microscopy (HSM) and thermogravimetric analysis (TGA) experiments.The synthesis and characterization of three new dispiro[indoline-3,3'-pyrrolizine-1',5''-thiazolidine] compounds are reported, together with the crystal structures of two of them. (3RS,1′SR,2′SR,7a’SR)-2′-(4-Chlorophenyl)-1-hexyl-2”-sulfanylidene-5′,6′,7′,7a’-tetrahydro-2′H-dispiro[indoline-3,3'-pyrrolizine-1',5''-thiazolidine]-2,4”-dione, C28H30ClN3O2S2, (I), (3RS,1′SR,2′SR,7a’SR)-2′-(4-chlorophenyl)-1-benzyl-5-methyl-2”-sulfanylidene-5′,6′,7′,7a’-tetrahydro-2′H-dispiro[indoline-3,3'-pyrrolizine-1',5''-thiazolidine]-2,4”-dione, C30H26ClN3O2S2, (II), and (3RS,1′SR,2′SR,7a’SR)-2′-(4-chlorophenyl)-5-fluoro-2”-sulfanylidene-5′,6′,7′,7a’-tetrahydro-2′H-dispiro[indoline-3,3'-pyrrolizine-1',5''-thiazolidine]-2,4”-dione, C22H17ClFN3O2S2, (III), were each isolated as a single regioisomer using a one-pot reaction involving L-proline, a substituted isatin and (Z)-5-(4-chlorobenzylidene)-2-sulfanylidenethiazolidin-4-one [5-(4-chlorobenzylidene)rhodanine]. The compositions of (I)-(III) were established by elemental analysis, complemented by high-resolution mass spectrometry in the case of (I); their constitutions, including the definition of the regiochemistry, were established using NMR spectroscopy, and the relative configurations at the four stereogenic centres were established using single-crystal X-ray structure analysis. A possible reaction mechanism for the formation of (I)-(III) is proposed, based on the detailed stereochemistry. The molecules of (I) are linked into simple chains by a single N-H…N hydrogen bond, those of (II) are linked into a chain of rings by a combination of N-H…O and C-H…S=C hydrogen bonds, and those of (III) are linked into sheets by a combination of N-H…N and N-H…S=C hydrogen bonds.Langbeinite-type compounds are a large family that include phosphates, sulfates and arsenates, and which are accompanied by interesting physical properties. This work reports a new disordered langbeinite-type compound, K2GdHf(PO4)3 [dipotassium gadolinium hafnium tris(phosphate)], and its structure as determined by single-crystal X-ray diffraction. Theoretical studies reveal that K2GdHf(PO4)3 is an insulator with a direct band gap of 4.600 eV and that the optical transition originates from the O-2p→Hf-5d transition. A Ce3+-doped phosphor, K2Gd0.99Ce0.01Hf(PO4)3, was prepared and its luminescence properties studied. With 324 nm light excitation, a blue emission band was observed due to the 5d1→4f1 transition of Ce3+. The average luminescence lifetime was calculated to be 5.437 µs and the CIE chromaticity coordinates were (0.162, 0.035). One may expect that K2Gd0.99Ce0.01Hf(PO4)3 can be used as a good blue phosphor for three-colour white-light-emitting diodes (WLEDs).Six two-dimensional (2D) coordination polymers (CPs), namely, poly[μ5-3,3-[(5-carboxylato-1,3-phenylene)bis(oxy)]dibenzoato-κ6O1O1′O3,O3′O5O5′bis(N,N-dimethylformamide-κO)lanthanide(III)], [Ln(C21H11O8)(C3H7NO)2]n, with lanthanide/Ln = cerium/Ce for CP1, praseodymium/Pr for CP2, neodymium/Nd for CP3, samarium/Sm for CP4, europium/Eu for CP5 and gadolinium/Gd for CP6, have been prepared by solvothermal methods using the ligand 3,3′-[(5-carboxy-1,3-phenylene)bis(oxy)]dibenzoic acid (H3cpboda) in the presence of Ln(NO3)3. The complexes were characterized by single-crystal X-ray and powder diffraction, IR spectroscopy, elemental analysis and thermogravimetric analysis (TGA). All the structures of this family of lanthanide CPs are isomorphous with the triclinic space group P-1 and reveal that they have the same 2D network based on binuclear LnIII units, which are further extended via interlayer C-H…π interactions into a three-dimensional supramolecular structure. The carboxylate groups of the cpboda3- ligands link adjacent LnIII ions and form binuclear [Ln2(RCOO)4] secondary building units (SBUs), in which each binuclear LnIII SBU contains four carboxylate groups from different cpboda3- ligands. Moreover, with the increase of the rare-earth Ln atomic radius, the dihedral angles between the aromatic rings gradually increase. Magnetically, CP6 shows weak antiferromagnetic coupling between the GdIII ions. The solid-state luminescence properties of CP2, CP5 and CP6 were examined at ambient temperature and CP5 exhibits characteristic red emission bands derived from the Eu3+ ion (CIE 0.53, 0.31), with luminescence quantum yields of 22%. Therefore, CP5 should be regarded as a potential optical material.Anion…π interactions are newly recognized weak supramolecular forces which are relevant to many types of electron-deficient aromatic substrates. Being less competitive with respect to conventional hydrogen bonding, anion…π interactions are only rarely considered as a crystal-structure-defining factor. Their significance dramatically increases for polyoxometalate (POM) species, which offer extended oxide surfaces for maintaining dense aromatic/inorganic stacks. The structures of tetrakis(caffeinium) μ12-silicato-tetracosa-μ2-oxido-dodecaoxidododecatungsten trihydrate, (C8H11N4O2)4[SiW12O40]·3H2O, (1), and tris(theobrominium) μ12-phosphato-tetracosa-μ2-oxido-dodecaoxidododecatungsten ethanol sesquisolvate, (C7H9N4O2)3[PW12O40]·1.5C2H5OH, (2), support the utility of anion…π interactions as a special kind of supramolecular synthon controlling the structures of ionic lattices. Both caffeinium [(HCaf)+ in (1)] and theobrominium cations [(HTbr)+ in (2)] reveal double stacking patterns at both axial sides of the aromatic frameworks, leading to the generation of anion…π…anion bridges. The latter provide the rare face-to-face linkage of the anions. In (1), every square face of the metal-oxide cuboctahedra accepts the interaction and the above bridges yield flat square nets, i.e. (HCaf+)2[SiW12O40]4-n. Two additional cations afford single stacks only and they terminate the connectivity. Salt (2) retains a two-dimensional (2D) motif of square nets, with anion…π…anion bridges involving two of the three (HTbr)+ cations. The remaining cations complete a fivefold anion…π environment of [PW12O40]3-, acting as terminal groups. This single anion…π interaction is influenced by the specific pairing of (HTbr)+ cations by double amide-to-amide hydrogen bonding. Nevertheless, invariable 2D patterns in (1) and (2) suggest the dominant role of anion…π interactions as the structure-governing factor, which is applicable to the construction of noncovalent linkages involving Keggin-type oxometalates.A series of five binary complexes, i.e. three cocrystals and two molecular salts, using 2-chloro-4-nitrobenzoic acid as a coformer have been produced with five commonly available compounds, some of pharmaceutical relevance, namely, 2-chloro-4-nitrobenzoic acid-isonicotinamide (1/1), C7H4ClNO4·C6H6N2O, 2-chloro-4-nitrobenzoic acid-3,3-diethylpyridine-2,4(1H,3H)-dione (2/1), 2C7H4ClNO4·C9H13NO2, 2-chloro-4-nitrobenzoic acid-pyrrolidin-2-one (1/1), C7H4ClNO4·C4H7NO, 2-carboxypiperidinium 2-chloro-4-nitrobenzoate, C6H12NO2-·C7H3ClNO4-, and (2-hydroxyethyl)ammonium 2-chloro-4-nitrobenzoate, C2H8NO+·C7H3ClNO4-. The coformer falls under the classification of a `generally regarded as safe’ compound. All five complexes make use of a number of different heteromeric hydrogen-bonded interactions. Intermolecular potentials were evaluated using the CSD-Materials module.MgCO3·MgCl2·7H2O is the only known neutral magnesium carbonate containing chloride ions at ambient conditions. According to the literature, only small and twinned crystals of this double salt could be synthesised in a concentrated solution of MgCl2. For the crystal structure solution, single-crystal diffraction was carried out at a synchrotron radiation source. The monoclinic crystal structure (space group Cc) exhibits double chains of MgO octahedra linked by corners, connected by carbonate units and water molecules. The chloride ions are positioned between these double chains parallel to the (100) plane. Dry MgCO3·MgCl2·7H2O decomposes in the air to chlorartinite, Mg2(OH)Cl(CO3)·nH2O (n = 2 or 3). This work includes an extensive characterization of the title compound by powder X-ray diffraction, thermal analysis, SEM and vibrational spectroscopy.A manuscript https://www.selleck.co.jp/products/resiquimod.html stilbene-based salicylhydrazone substance systematic name (E)-4,4′-(ethene-1,2-diyl)bis[(N'E)-N'-(2-hydroxybenzylidene)benzohydrazide] dimethyl sulfoxide disolvate, C30H24N4O4·2C2H6OS or L·2DMSO ended up being synthesized along with characterized by single-crystal X-ray diffraction, powdered ingredients X-ray diffraction along with luminescence spectroscopy.
