Abstract
In the title triangulo-triruthenium compound, [Ru3(C25H22As2)(C19H17OP)(CO)9], the bis(diphenylarsino)methane ligand bridges a 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. Additionally, each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three phosphine substituted phenyl rings make dihedral angles of 74.34 (12), 68.34 (12) and 85.45 (11)° with each other. The dihedral angles between the two phenyl rings are 87.56 (11) and 60.56 (11)° for the two diphenylarsino groups. In the crystal packing, the molecules are linked together into chains via intermolecular C—H⋯O hydrogen bonds down the a axis. Weak intermolecular C—H⋯π interactions further stabilize the crystal structure.
