HLOROBIS(1,3-IMIDAZOLIDINE-2-THIONE-S)-CADMIUM(II)

The redetermination of the crystal structure of a cadmium(II) complex of 1,3-imidazolidine-2-thione (Imt) coordinated with two molecules of Imt and two Cl- ions, [CdCl2(C3H6N2S)(2)], has been performed in order to obtain accurate parameters and to study the effects of the metal c oordination on the metal-S and C-S bonds in Imt complexes. The Cd-I-S distances of 2.525(2) and 2.535 (2) Angstrom in the present tetrahedra l complex are significantly longer than the corresponding distances in the Au-I and Cu-II complexes of Imt, but there is no significant diff erence in the C-S distances of 1.721 (6) and 1.710 (6) Angstrom from t hat in Au-I and Cu-II complexes. This work represents a significant in crease in the quality of the structure of the title compound over the earlier work.
