Abstract
The reaction of Rh-6(CO)(15)MeCN With allyldiphenylphosphine under mild con ditions afforded the cluster-containing complex [Rh-6(CO)(14)(mu,eta(2)-PPh 2CH2CH=CH2)]. Its molecular structure was characterized. The resulting comp lex is an octahedral Rh cluster with ten terminal and four mu(3)-bridging C O ligands. The average Rh-Rh distance is 2.762(2) Angstrom. The unsaturated ligand is additionally coordinated to the metal center (Rh(4)-C(232), 2.37 (1) Angstrom; and Rh(4)-C(233), 2.32(2) Angstrom) to form a pi-bond.
