Undeca-carbonyl-1κC,2κC,3κC-[tris-(3-chloro-phen-yl)phosphine-1κP]-triangulo-triruthenium(0)

In the title triangulo-triruthenium compound, [Ru(3)(C(18)H(12)Cl(3)P)(CO)(11)], one equatorial carbonyl group has been substituted by the monodentate phosphine ligand, leaving one equatorial and two axial carbonyl substituents on the Ru atom. The remaining two Ru atoms each carry two equatorial and two axial terminal carbonyl ligands. The three benzene rings make dihedral angles of 87.83 (17), 69.91 (17) and 68.26 (17)° with each other. In the crystal structure, mol-ecules are linked into dimers by inter-molecular C-H⋯O hydrogen bonds. The mol-ecular structure is stabilized by an intra-molecular C-H⋯O hydrogen bond.
