The reaction of Rh₆(CO)₁₅MeCN with allyldiphenylphosphine under mild conditions afforded the cluster-containing complex [Rh₆(CO)₁₄(μ,η²-PPh₂CH ₂CH=CH₂)]. Its molecular structure was characterized. The resulting complex is an octahedral Rh cluster with ten terminal and four μ₃-bridging CO ligands. The average Rh - Rh distance is 2.762(2) A. The unsaturated ligand is additionally coordinated to the metal center (Rh(4) - C(232), 2.37(1) A; and Rh(4) - C(233), 2.32(2) A) to form a π-bond.
