metal-organic compounds
In the title compound, [Zn2(C7H4O2S)2(C12H8N2)2], the Zn complex forms a centrosymmetric dimer with a ZnZn separation of 3.580 (1) Å. Each Zn atom is coordinated by two N atoms from the 1,10-phenanthroline (phen) ligand and by three O atoms and one S atom from the thiosalicylate ligands in a highly distorted octahedral geometry, with Zn—N distances of 2.119 (2) and 2.166 (2) Å, Zn—O distances in the range 2.161 (2)–2.329 (2) Å, and a Zn—S distance of 2.3034 (12) Å. There are π–π stacking interactions between the phen rings, forming a stacking arrangement along the c axis in the crystal structure.
organic compounds
In the title molecule, C14H10O4S, all bond lengths and angles are normal. In the crystal structure, strong intermolecular O—HO hydrogen bonds between the carboxyl groups link the molecules into zigzag chains extending along the c axis.
organic compounds
The title compound, C13H14N2·C8H6O4, was obtained by the hydrothermal reaction of CuCl with 1,2,4,5-benzenetetracarboxylic acid and 1,3-bis(4-pyridyl)propane. The 1,3-bis(4-pyridyl)propane molecule lies on a crystallographic twofold axis, and terephthalic acid is on an inversion centre. In the crystal structure, strong intermolecular O—HN hydrogen bonds between the components lead to the formation of zigzag chains extending along [10]. The chains are linked through intermolecular C—HO hydrogen bonds.
organic compounds
The title compound, C10H8N2·2C7H5NO4, was obtained as a by-product of the hydrothermal reaction of ZnSO4 with 2-nitrobenzoic acid and 4,4′-bipyridine. The 4,4′-bipyridine molecule lies on an inversion centre. There are O—HN and C—HO hydrogen bonds between the components in the crystal structure.
