Novel rhodium and ruthenium carbonyl cluster complexes with face-and edge-bridging GaCp~* ligands. Synthesis and structural characterization of the Rh_6(CO)_(12)(mu_3-GaCp~*)_4 and Ru_6(eta~6-C)(mu_2-CO)(CO)_(13)(mu_3-GaCp~*)_2(mu_2-GaCp~*)clusters

摘要

Reactions of hexanuclear carbonyl clusters of rhodium Rhs-(CO)_(16) and ruthenium Ru_6(eta~6-C)(mu_2-CO)(CO)_(16) with GaCp~* (Cp~* = C_5Me_5) in the mild conditions result in substitution of CO ligands and formation of the Rh_6(CO)_(12)(mu_3-GaCp~*)_4 and the Ru_6(eta~6-C)(mu_2-CO)(CO)_(13)(mu_3-GaCp~*)_2(mu_2-GaCp~*) cluster derivatives.
