The title compound, [CuCl2(C12H12N2)]n, was obtainedviaa DMSO-mediated dehydration of Cu(4,4′-dimethyl-2,2′-bipyridine)copper(II)·0.25H2O. The central CuIIatom is coordinated in a distorted trigonal–bipyramidal geometry by two N atoms of a chelating 4,4′-dimethyl-2,2′-bipyridine ligand [average Cu—N = 2.03 (3) Å] and three Cl atoms, one terminal with a short Cu—Cl bond of 2.2506 (10) Å, and two symmetry-equivalent and bridging bonds. The bridging Cl atom links the CuIIions into chains parallel to [001]viaone medium and one long Cu—Cl bond [2.3320 (10) and 2.5623 (9) Å]. The structure displays both inter- and intramolecular C—H...Cl hydrogen bonding.

In the title compound, [CdBr2(C11H10N2)(C2H6OS)], the CdIIatom is five-coordinated in a distorted trigonal–bipyramidal geometry by two N atoms from a 6-methyl-2,2′-bipyridine ligand, one O atom from a dimethyl sulfoxide ligand and two Br atoms. An intramolecular C—H...O hydrogen bond occurs. The crystal structure is stabilized by C—H...Br hydrogen bonds and π–π contacts between the pyridine rings [centroid–centroid distances = 3.582 (5) and 3.582 (5) Å].

The title compound, [Sn2Cl2(CH3)4(C6H5N2O2)2], forms infinite one-dimensional zigzag chains that propagate in a helical fashion along the c axis via an Sn—O=C—O—Sn—O bridge which involves the carboxylate groups of two methylpyrazinecarboxylate ligands. These display both chelating and bridging coordination behaviour. The asymmetric unit contains two Sn atoms; one adopts a distorted trigonal–bipyramidal geometry, while the other is in a distorted pentagonal–bipyramidal configuration.

In the dinuclear title compound, [Na2(C13H15ClN5O5S)2(H2O)6] n , two Na+ cations, disposed about a centre of inversion, are linked by two bridging water molecules. The coordination geometry is based on an O5 donor set defined by four water molecules and a 4-aminobenzenesulfonate O atom in a distorted trigonal–bipyramidal geometry. In the crystal, significant O—H...O, O—H...N and N—H...O hydrogen bonds lead to the formation of a three-dimensional architecture.

One ZnIIcation adopts a distorted trigonal bipyramidal geometry and the other a square-pyramidal geometry. The two acetate ligands bridge two ZnIIcations with mono- and bidentate coordination modes. The title compound exhibits a strong emission at 460 nm upon excitation at 325 nm with a quantum yield of 23.1%.

The title compound, [Ge2(C8H17N2)4O2], crystallizes with imposed twofold symmetry, which allows the monodentate amidinate ligands to be arranged in acisoidfashion. The independent Ge—O distances within the central Ge2O2ring, which is essentially planar (r.m.s. deviation = 0.039 Å), are 1.7797 (8) and 1.8568 (8) Å. The germanium centres adopt a distorted trigonal–bipyramidal geometry, being coordinated by the two O atoms and by one bidentate and one monodentate amidinate ligand (three N atoms). OneN-isopropyl group is disordered over two positions; these are mutually exclusive because of `collisions' between symmetry-equivalent methyl groups and thus each has 0.5 occupancy.
