The high-pressure (1300 psi CO, 120°C) reactions of Ru3(CO)12 with the diphosphines R2PCH2PR2; R = CH3 (dmpm), C6H5 (dppm), and C6H11 (dcypm), are reported. In the case of dppm, the disphosphine-bridged dinuclear ruthenium complex [Ru2(μ-dppm)2(μ-CO)(CO)4] was obtained. The corresponding reaction with dcypm afforded the mononuclear chelated diphosphine complex [Ru(dcypm)(CO)3]. The mixed ligand system [Ru2(μ-dppm)(μ-dmpm)(μ-CO)(CO)4] was obtained by employing a 1 : 1 mixture of dppm and dmpm. The crystal and molecular structures of [Ru2(μ-dppm)2(μ-CO)(CO)4] and [Ru(dcypm)(CO)3] were also determined.
