| Sumario: | In title compound, [CuC1(C10H8N2S2)]n, (I) each Cu(I) ion coordinates to two nitrogen atoms from two different ligands and to two chloro ions which bridge to another Cu(I) to complete a planar four-membered Cu2Cl2 ring.The Cu+ coordination geometry is best described as a slightly distorted tetrahedron. The structure consists of CuCl cores connected by 2, 2'-dypyridyldisulfide ligand and form a two-dimensional extended polymeric network in which the 2, 2'-dipyridyldisulfide ligand bridges Cu atoms. The title compound is isostructural with di-u-chlorido-bis[(di-2-pyridyldisulnde-K² N, N') copper(I)], (II)', which is a zero-dimensional binuclear compound. The two structures differ due conformational flexibility of ligand, which have axial conformation in (I) and equatorial conformation in (II), torsion angles S-S-C-N (axial ring) 168.8(4)°; for (I) and 72.0(3)° for (II) respectively. |
