title: Octa-carbonyldi-μ(2)-hydrido-[μ(3)-(1,3,5-trimethyl-phen-yl)phosphinidene](tri-phenyl-phosphane)-triangulo-triruthenium.
abstract: In the crystal structure of the title compound, [Ru(3)(C(9)H(11)P)H(2)(C(18)H(15)P)(CO)(8)], the triangular Ru(3) unit is capped with one mesitylphosphin-idene ligand. In the trigonal-pyramidal Ru(3)P core, one Ru(II) atom is coordinated by a triphenyl-phosphane ligand in a terminal fashion. Two hydride ligands bridge over two Ru-Ru bonds. These Ru-Ru bonds [2.9400 (4) and 2.9432 (4) Å] are slightly longer than the nonhydride-bridged Ru-Ru bond [2.8146 (4) Å]. The terminal triphenyl-phosphane ligand coordinates to the Ru(II) atom, which is involved in two hydride bridges.
