| Abstract: | ESR studies of the interaction between Co(C5H7O2)2 and Al(C2H5)3 in presence of CO reveal the formation of paramagnetic tri- and tetra-nuclear carbonyl compounds and the consecutive formation of complexes including one, two and three cobalt atoms. Al(C2H5)3 decomposition is suggested to take place on the reduced transition metal to form Co–Al clusters. Structures for the paramagnetic heteronuclear clusters is proposed.
