Dichlorobis(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 coordination on the metal-S and C-S bonds in Imt complexes. The Cd^I-S distances of 2.525 (2) and 2.535 (2) Å in the present tetrahedral complex are significantly longer than the corresponding distances in the Au^I and Cu^II complexes of Imt, but there is no significant difference in the C-S distances of 1.721 (6) and 1.710 (6) Å from that in Au^I and Cu^II complexes. This work represents a significant increase in the quality of the structure of the title compound over the earlier work.
