Structural studies of metal complexes with NN′-disubstituted thioureas. Part II. Crystal structure of dichlorobis-(NN′-diethylthiourea)cobalt(II)(triclinic form)

Abstract

The crystal structure of the title compound has been determined by the heavy-atom method and refined by anisotropic least-squares methods to R 0·101 for 1303 visually estimated independent reflections. Crystals are triclinic, space group P, with Z= 2, in a unit cell of dimensions: a= 8·931, b= 9·082, c= 15·024 Å, α= 64° 24′, β= 119° 56′, γ= 111° 24′. The structure consists of polymeric chains of molecules connected to each other by hydrogen bonds between the chlorine and NH groups. The cobalt is tetrahedrally co-ordinated: mean Co–S 2·323, and Co–Cl 2·254 Å.
