Abstract

The crystal and molecular structure of a 2:1 complex of CoCl2 with DETP (N,N,N′,N′-tetraethylpyridine-2,6-dithiocarboxamide), has been determined. The compound is built up from {Co(DETP)(Cl)}+ and [Co2Cl4(μ 2−Cl)2]2− groups. The cobalt atom in the cation is bonded to two sulphur atoms, a pyridilic nitrogen atom of the DETP ligand, and a chlorine atom in a distorted square planar geometry. The {Co(DETP)(Cl)}+ units are stacked over each other in a staggered manner so that each cobalt atom interacts weakly with a sulphur atom of a unit above and below it. The anionic cobalt is present as the centrosymmetric [Co2Cl4(μ 2−Cl)2]2− ion in which two chlorine bridges complete tetrahedral coordination about the cobalt atoms.
