The title compound, [CuCl(C13H14N2)] n, adopts an infinite one-dimensional chain structure. The CuI atom, which lies on a crystallographic mirror plane, is coordinated by the N atom from two pyridyl rings [Cu—N = 1.975 (7) Å] and a Cl atom [Cu—Cl = 2.251 (4) Å] in a trigonal-planar geometry. The Cl atom also lies on the mirror plane.< [ABSTRACT FROM AUTHOR]

The title compound, [ZnII(C8H8O6)(C8H8N2)(H2O)2] n, contains a Zn atom coordinated by 4,4′-bipyridine, benzene-1,4-dioxy­diacetate and two water mol­ecules. The Zn atom lies on an inversion centre and the benzene-1,4-dioxy­diacetate and 4,4-bipyridine ligands lie about other inversion centres. [ABSTRACT FROM AUTHOR]

The title compound, [Sm2(C10H2O8)(C10H4O8)(H2O)2] n or [Sm2(btec)(H2btec)(H2O)2] n, was synthesized hydro­­thermally by the reaction of Sm2O3 with 1,2,4,5-ben­zene­tetra­carboxylic acid (H4btec). The Sm atom is coordinated by nine O atoms, three from H2btec2−, five from btec4− and one from a coordinated water mol­ecule. Sm—O distances range from 2.376 (3) to 2.558 (5) Å.

In the title compound, [Zn2(C7H4O2S)2(C12H8N2)2], the Zn complex forms a centrosymmetric dimer with a Zn⋯Zn 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. [ABSTRACT FROM AUTHOR]

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—H⋯N and C—H⋯O hydrogen bonds between the components in the crystal structure. [ABSTRACT FROM AUTHOR]

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—H⋯N hydrogen bonds between the components lead to the formation of zigzag chains extending along [10 ]. The chains are linked through inter­molecular C—H⋯O hydrogen bonds. [ABSTRACT FROM AUTHOR]

In the title mol­ecule, C14H10O4S, all bond lengths and angles are normal. In the crystal structure, strong inter­molecular O—H⋯O hydrogen bonds between the carboxyl groups link the mol­ecules into zigzag chains extending along the c axis. [ABSTRACT FROM AUTHOR]

In the title compound, [Co(C12H8N2)2(C17H8O9)]·H2O, the Co atom is octa­hedrally coordinated by four N atoms from two 1,10-phenanthroline (phen) ligands and two O atoms from the 2-carb­oxy-4-(4-carb­oxy-3-carboxyl­atobenzo­yl)benzoate ligand. O⋯H⋯O hydrogen bonds link this discrete structure into a one-dimensional chain. [ABSTRACT FROM AUTHOR]
