The asymmetric unit of the title triangulo-triruthenium compound, [Ru3(C25H22As2)(C19H17P)(CO)9], consists of two crystallographically independent molecules of the triangulo-triruthenium complex, A and B. The bis(diphenylarsino)methane ligand bridges an Ru-Ru bond and the monodentate phosphine ligand bonds to the third Ru atom. Both the phosphine and arsine ligands are equatorial with respect to the Ru3 triangle. In addition, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. With regard to the three phosphine-substituted rings, the benzyl ring makes dihedral angles of 41.0 (3) and 43.9 (3)° with the other two benzene rings in molecule A; these angles are 49.8 (3) and 56.8 (3)° in molecule B. The dihedral angles between the two benzene rings are 76.1 (3) and 88.2 (3)° for the two diphenylarsino groups in molecule A and 71.3 (3) and 78.1 (3)° in molecule B. In the crystal packing, molecules are linked into chains via intermolecular C-H...O hydrogen bonds. Weak intermolecular C-H...[pi] interactions further stabilize the crystal structure.
