Abstract

The monoclinic form of dichlorobis(N,N'-diethylthiourea)cobalt(II) [CoCl2(detu)2] (1) was synthesized and characterized by single crystal X-ray diffraction (space group P21/c, a= 10.439(2), b= 14.964(2), c = 24.005(3)Å, β = 92.00(1)°, Z = 8). The solid state structure is described and compared with that of the triclinic form previously reported. The asymmetric unit consists of two independent complex molecules, in which the cobalt ions show distorted tetrahedral coordination by two sulfurs from the detu ligands and two chloride ions.
