Cadmium heterometallic compounds: Classification and analysis of crystallographic and structural data

Abstract

Cadmium chemistry is an important area of research from both an industrial and environmental point of view. This review surveys the structural determination of almost ninety heterometallic complexes of cadmium. The cadmium atom is found mostly in the oxidation state of +2, but there are also examples of +1 and zero. The coordination numbers observed range from two to eight, with six occurring most frequently. The heterometal atoms include both transition and non-transition metals. A range of derivatives from dimers to polymers contain two or more metal atoms, however, there appears to be no evidence to suggest the existence of a direct Cd-Cd metal bond. © 1995, by Walter de Gruyter GmbH & Co.
