Abstract The crystal structures of the pyribencarb E and Z stereoisomers were determined using single-crystal X-ray crystallography. isomers confirmed a single data respectively by analysis, LC-UVD mass spectrometry, NMR spectroscopy. Pyribencarb crystallizes in triclinic P − 1 isomer monoclinic 2 / c, with showing comparable packing motifs. Moreover, molecular docking was carried out cytochrom...
A 1:1 co-crystal of rac-trans-1,2-C(6)H(10)(OH)(2) and (C(6)H(5))(3)PO has been found that is unusual because there are no strong interactions between the two kinds of molecules, which are segregated into layers. Furthermore, neither pure rac-1,2-cyclohexanediol (CHD) nor pure triphenylphosphine oxide (TPPO) has any obvious packing problem that would make the formation of inclusion complexes li...
The crystal structures of 4-(4-methylphenyl)-6-phenyl-2,3,3a,4-tetrahydro-1H-pyrido[3,2,1-jk]carbazole (IIa) and 4-(4-methoxyphenyl)-6-phenyl-2,3,3a,4-tetrahydro-1H-pyrido[3,2,1-jk]carbazole (IIb) were elucidated by single crystal X-ray diffraction. Compound (IIa), C28H25N, crystallizes in the triclinic system, space group P-1, with a = 8.936(2) Å, b = 10.490(1) Å, c = 11.801(1) Å, α = 102.69(5...
The title crystal structure is a new triclinic polymorph of [(Ph3P)2N]Cl·(B(OH)3) or C36H30NP2 (+)·Cl(-)·BH3O3. The crystal structure of the ortho-rhom-bic polymorph was reported by [Andrews et al. (1983 ▶). Acta Cryst. C39, 880-882]. In the crystal, the [(Ph3P)2N](+) cations have no significant contacts to the chloride ions nor to the boric acid mol-ecules. This is indicated by the P-N-P angle...
The synthesis and crystal structure of the one-dimensional coordination polymer, [Cd(spar)2]n·n(H2O), are described, where spar is the sparfloxacinate anion, C19H21N4O3F2. The Cd ion is bonded to four spar ligands: Two O,O-chelate with their β-keto carboxylate groupings and two are monodentate-bound through a carboxylate O atom, to result in a distorted CdO6 octahedral coordination geometry. Th...
Zinc (II) complex, [Zn(25-MBTSC)2I2] (1), where (25-MBTSC = (E)-2-(2,5-dimethoxybenzaldehyde) thiosemicarbazone, has been synthesized from the reaction of ZnI2 with 25-MBTSC in methanol as solvent at 25 ºC. It was characterized by elemental analysis (CHN) and is confirmed by single-crystal X-ray diffraction analysis. The complex 1 crystallizes in a triclinic system, with space group P-ī, having...
The reaction of cadmium(II) nitrate hexahydrate with the proton-transfer compound (pipzH2)(ox) (where pipz=piperazine and oxH2=oxalic acid), in aqueous solution leads to the formation of the title polymeric compound (C2H6CdO7)n. This compound crystallizes in the triclinic system, space group Pī with two formula in the unit cell. The unit cell parameters are: a = 5.998 (4) Å, b = 6.634 (5) Å, c ...
A new azo-Schiff base"Ethyl 2-((E)-(4-((E)-(4-ethylphenyl)diazenyl)-2-hydroxybenzylidene)amino)-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate" was prepared by the reaction of "Ethyl 2-amino-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate" and "(E)-5-((4-ethylphenyl)diazenyl)-2-hydroxybenz aldehyde" (1:1 molar ratio) in MeOH under reflux condition. The structure of compound was studied by ...

This paper covers nineteen Pt(II) complexes of the composition Pt(η3-X1X2X3)(PR3), (X = N1, N2, N3; S1, S2, S3; or Te1, Te2, Te3). These crystallized in three crystal classes: triclinic (eleven examples), monoclinic (six and orthorhombic (two examples). Each tridentate ligand creates two metallocyclic rings with common Te2 donor ligands types N1C2N2C2N3, N1C2N2NC2N3, S1C2S2C2S3, S1C3S2C3S3, Te1...
