[μ-Bis(diphenyl­arsanyl)methane-1:2κ(2) As:As’]nona­carbonyl-1κ(3) C,2κ(3) C,3κ(3) C-[(4-methyl­sulfanylphen­yl)diphenyl­phosphane-3κP]-triangulo-triruthenium(0)

In the title triangulo-triruthenium compound, [Ru(3)(C(25)H(22)As(2))(C(19)H(17)PS)(CO)(9)], the bis­(diphenyl­arsanyl)methane ligand bridges an Ru—Ru bond and the monodentate phosphane ligand bonds to the third Ru atom. Both arsine and phosphane 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 three phosphane-substituted benzene rings make dihedral angles of 57.91 (19), 84.31 (15) and 59.37 (18)° with each other. The dihedral angles between the two benzene rings are 60.9 (2) and 85.40 (18)° for the two diphenyl­arsanyl groups. In the crystal, mol­ecules are linked into a three-dimensional framework by inter­molecular C—H⋯O hydrogen bonds. Weak inter­molecular C—H⋯π inter­actions stabilize the crystal structure.
