[μ-Bis(diphenyl­arsino)methane-1:2κ2 As:As′]nona­carbonyl-1κ3 C,2κ3 C,3κ3 C-[(penta­fluoro­phen­yl)diphenyl­phosphine-3κP]-triangulo-triruthenium(0) chloro­form monosolvate

The asymmetric unit of the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(18)H(10)F(5)P)(CO)(9)]·CHCl(3), contains one mol-ecule of the triangulo-triruthenium complex and one mol-ecule of the disordered chloro-form solvent. The bis-(diphenyl-arsino)methane ligand bridges an Ru-Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru(3) triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The phosphine-substituted benzene rings make dihedral angles of 68.43 (15), 65.14 (14) and 89.75 (14)° with each other. The dihedral angles between the two benzene rings are 80.70 (15) and 84.53 (16)° for the two diphenyl-arsino groups. In the crystal packing, the mol-ecules are linked into a plane parallel to bc by inter-molecular C-H⋯O and C-H⋯F hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions further stabilize the crystal structure.
