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 asymmetric unit of the title compound, [CuBr(C18H18N4)]Br, there are three crystallographically independent cations. One of the cations exhibits positional disorder of the pyridin-2-ylmethyl groups over two sets of sites with refined occupancies of 0.672 (8) and 0.328 (8). The outer-sphere bromine counter-ion is severely disordered over multiple sites. In each cation, the CuIIion is coordinated by the four N atoms of the tris(pyridin-2-ylmethyl)amine ligand and one bromine and adopts a slightly distorted trigonal–bipyramidal geometry.

The crystal structure of the title compound, tetra-μ2-(cyclopent-2-enyl)acetato-1:2κ2 O:O′;1:3κ2 O:O′;2:4κ2 O:O′;3:4κ2 O:O′-octamethyl-1κ2 C,2κ2 C,3κ2 C,4κ2 C-di-μ3-oxo-1:2:3κ3 O;2:3:4κ3 O-tetratin(IV), [Sn4(CH3)8(C7H9O2)4O2], is composed of discrete centrosymmetric dimers lying about inversion centres. The cyclopentenylacetate ligand shows different modes of coordination with Sn, as a result of which the central Sn2O2 core is fused with two four-membered (Sn2O2) and two six-membered (Sn2O3C) rings. The endocyclic Sn atoms are six-coordinate in a skew-trapezoidal bipyramidal environment. The exocyclic Sn atoms are five-coordinate and show distorted trigonal–bipyramidal geometry. The Sn—C distances lie in a very narrow range [2.095 (4)–2.113 (4) Å], while the Sn—O distances range between 2.030 (3) and 2.280 (3) Å for strong bonds and a value of 2.654 (3) Å for the relatively weak Sn—O bond.

In the title compound, [Zn2(C3N3S3)(C9H23N3)2]ClO4·H2O, the dinuclear ZnII metal centres are bridged by a trithiocyanurate(3-) anion (ttc), with each centre having a distorted trigonal bipyramidal geometry and bonded to three diethylenetriamine N atoms, and an S and an N atom of ttc. The crystal structure is stabilized by O—H...O, O—H...S, C—H...S and C—H...O interactions connecting the cations, the ClO4 − anions and the water molecules.

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.
