The colour isomerism and structure of some copper co-ordination compounds / T.N.M. Waters

Abstract

Following the classical work of Werner whose co-ordination theory provided the first rational foundation for the study of transition metal complexes, chemists have endeavoured to discover the underlying principles involved in these compounds. Thus, while Werner noticed the directional property of the bonds between metal and ligand, it was not until Pauling (1931) and others were able to apply a wave mechanical treatment, that an explanation for the rigid stereochemical requirements of the metal was found. With this growth in fundamental knowledge the interpretation and use of the physical properties of complex compounds has become possible. For example, the magnetic susceptibility has been related to the electronic configuration of the metal atom, (Pauling loc. cit.) enabling predictions to be made about the type of metal-ligand bond.
