The title coordination polymer, [Zn(C6H4NO3)2] n , was prepared under hydro-thermal conditions by the reaction of zinc nitrate with 5-hy-droxy-nicotinic acid in the presence of malonic acid. In the structure, the Zn(II) ion is coordinated by two carboxyl-ate O atoms and two pyridine N atoms of four 5-hy-droxy-nicotinate ligands in a distorted tetra-hedral coordin-ation environment. The μ2-bridging mode of each anion leads to the formation of a three-dimensional framework structure. Inter-molecular hydrogen bonds between the hy-droxy groups of one anion and the non-coordinating carboxyl-ate O atoms of neighbouring anions consolidate the crystal packing.

A novel coordination compound, [Co()(HO)], was synthesized from aqueous solutions of Co(NO) and the ligand 2-[(5-methyl-1,3,4-thia-diazol-2-yl)sulfan-yl]acetic acid (H, CHNOS). In the monoclinic crystals (space group 2/), the cobalt(II) ion is located about a centre of symmetry and is octa-hedrally coordinated by two anions in a monodentate fashion through carboxyl O atoms and by four water mol-ecules. A relatively strong hydrogen bond between one of the water mol-ecules and the non-coordinating carboxyl-ate O atom consolidates the conformation.

The asymmetric unit of the title compound, [Co(CBrO)(CHN)(HO)] or [Co(Brbdc)(im)(HO)] , comprises half of Co ion, tetra-bromo-benzene-dicarboxylate (Brbdc), imidazole (im) and a water mol-ecule. The Co ion exhibits a six-coordinated octa-hedral geometry with two oxygen atoms of the Brbdc ligand, two oxygen atoms of the water mol-ecules, and two nitro-gen atoms of the im ligands. The carboxyl-ate group is nearly perpendicular to the benzene ring and shows monodentate coordination to the Co ion.

The title compound, bis-[μ-2,2'-(4-1,2,4-triazole-3,5-di-yl)di-acetato]-bis-[di-aqua-copper(II)] dihydrate, [Cu(CHNO)(HO)]·2HO, is a dinuclear octa-hedral Cu triazole-based complex. The central copper atoms are hexa-coordinated by two nitro-gen atoms in the equatorial positions, two equatorial oxygen atoms of two carboxyl-ate substituents in position 3 and 5 of the 1,2,4-triazole ring, and two axial oxygen atoms of two water mol-ecules. Two additional solvent water mol-ecules are linked to the title mol-ecule by O-H⋯N and O⋯H-O hydrogen bonds.
