摘要：

Reaction of the coordinatively unsaturated complex [Cp*Ru(mu-OMe)]2 with Ph2SiH2 produces {[eta5-C5Me5)Ru]2(mu-SiPhOMe)(mu-OMe)(mu-H)}, via substitution of a phenyl group on silicon by methoxide. The structure reveals a Ru-Ru double bond, d(Ru-Ru) = 2.569 (5) angstrom, which is bridged by the phenyl(methoxy)silylene ligand, a methoxy group, and a hydride ligand (not located). Crystal data: triclinic, a = 11.157 (7) angstrom, b = 16.336 (8) angstrom, c = 16.792 (7) angstrom, alpha = 74.39 (4)-degrees, beta = 88.13 (5)-degrees, gamma = 74.71 (5)-degrees, V = 2841 (3) angstrom3, Z = 2, and R = 6.69%. The related reaction with CyMeSiH2 (Cy = cyclohexyl) takes a different course, but also proceeds via Si-O bond formation to give CyMeSiH(OMe) and {[Cp*Ru(mu-eta2-H-SiMeCy)]2(mu-H)(H)}.
