The authors discovered and investigated new types of stable heterometallic carboxylate complexes in which divalent transition metal atoms of the 4th period of the Periodic Table of Chemical Elements (V, Co, Ni, Cu, Zn) combine with atoms of lithium, magnesium, calcium or rare earth elements. These polynuclear heterometallic compounds retain their structure under conditions when the homometallic compounds of these transition metals decompose to mononuclear complexes. The different metals combination in one molecule allows us to use the obtained heterometallic compounds for producing disperse and film oxide materials, and bimetallic oxide catalysts. The stability of the complexes allows to immobilize them in various matrices and to assemble 3D polymer structures on their base. Since the metal ions under consideration (V, Co, Ni, Cu, Zn) are capable to form isostructural heterometallic compounds, it becomes possible to obtain compounds within a single structural type with a given combination of physical properties, determined by the nature of the metal ions.
