Abstract

Reactions of CuCl2 with 1.3.5-trithiane and 1.4.7-trithiacyclononane yield crystals of CuCl2· C3H6S3, and CuCl2• C6H12S3, resp. According to X-ray structure analyses, CuCl2• C3H6S3 forms infinite chains, whereas CuCl2• C6H12S3 consists of discrete molecules. In CuCl2• C3H6S3 the thioether molecules act as bridging ligands. Each Cu is coordinated to two S atoms belonging to two adjacent ligands, and to two Cl atoms; thus a distorted square planar coordination results. In CuCl2· C6H12S3 the Cu is penta-coordinated to the three S atoms of the ligand and to two Cl atoms. One Cu–S bond is significantly longer than the two others; the coordination polyhedron may be regarded as a distorted tetragonal pyramid.
