The anionic cluster (HRu{sub 3}(CO){sub 8}({mu}-PPh{sub 2}){sub 2}){sup {minus}} (1) is obtained from the reaction of (HRu{sub 3}(CO){sub 11}){sup {minus}} with PPh{sub 2}H in THF solution. The solid-state structure of 1 has been determined by a single-crystal X-ray analysis of the bis(triphenylphosphine)iminium salt. Crystals are triclinic, space group P{anti 1}, with Z = 2 in a unit cell of dimensions a = 14.690 (6), b = 18.652 (4), c = 12.150 (2) {angstrom}, {alpha} = 106.60 (2), {beta} = 92.17 (2), {gamma} = 95.89 (2){degree}. The reaction of 1 with Wilkinson's catalyst, (PPh{sub 3}){sub 3}RhCl, leads to the formation of (H{sub 2}Ru{sub 3}Rh({mu}-CO)(CO){sub 6}(PPh{sub 3}){sub 2}({mu}-PPh{sub 2})(PPhC{sub 6}H{sub 4})) (2), and with Vaska's complex, (PPh{sub 3}){sub 2}Ir(CO)Cl, the cluster (H{sub 2}Ru{sub 3}Ir({mu}-CO)(CO){sub 7}(PPh{sub 3})({mu}-Pph{sub 2})(PPhC{sub 6}H{sub 4})) (3) is obtained.
