Direct Synthesis of Hetero Bimetallic Complexes

Abstract

The concept of direct synthesis (the use of metals or their oxides as the starting materials for obtaining coordination compounds) has been further developed as “anion-deficient” and “ligand-deficient” methods for synthesis of heterometallic complexes. We have used the example of coordination compounds with amino alcohols and ethelenediamines to demonstrate the advantages of the proposed approach for obtaining polynuclear, mixed-anion, and mixed-valence heterometallic complexes. We present the most interesting crystal structures of the Cu–M (Co, Zn, Cd, Pb) hetero bimetallic complexes. It is shown that direct synthesis of hetero trimetallic complexes can be a further possible development of the new concept.
