ABSTRACT OF THE DISCLOSURE Broadly stated, the present invention encompasses tetranuclear sulfide-bridged complexes of Cr(III) having bridging organo-carboxylate ligands. Indeed, in one embodiment, the present invention is directed toward a novel composition of matter having a complex cation of the general formula Cr4S(RCO2)g(L)42+, wherein R represents alkyl groups having from 1 to 12 carbon atoms, L represents a ligand or ligands containing a donor atom selected from oxygen, nitrogen, carbon, and sulfur. In the complex of the present invention, the four Cr(III) atoms are bound to a central tetrahedral sulfur atom. The chromium atoms also are octahedrally coordinated with bridging carboxylates and the ligand molecule. Also, the bridging carboxylates, RCO2 of the above formula, are the same or different carboxylates.
