catena-Poly[[chlorido-tris-(1,3-thia-zolidine-2-thione-κS)cadmium(II)]-μ-chlorido].

The synthesis and characterization of poly[di-chlorido-tri(1,3-thia-zolidine-2-thione)cadmium(II)], [CdCl2(C3H5NS2)3] n , prepared from CdCl2·H2O and C3H5NS2 (tzdSH) in a 1:3 ratio, are described. The CdII cation is coordinated by three 1,3-thia-zolidine-2-thione mol-ecules and three Cl- anions in a distorted octa-hedral environment. The Cd metal centres are connected via Cl- ligands, creating polymeric chains running along the a-axis direction. The conformation of the chains is stabilized by N-H⋯Cl hydrogen bonds.
