Abstract
The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru3(C21H21AsS3)(C25H22P2)(CO)9]·CH2Cl2, consists of one triangulo-triruthenium complex molecule and one half of a dichloromethane molecule which lies across a crystallographic inversion center, leading to the disorder of this molecule over two positions of equal occupancy. The bis(diphenylphosphino)methane ligand bridges an Ru—Ru bond and the monodentate arsine ligand bonds to the third Ru atom. Both the arsine and phosphine ligands are equatorial with respect to the Ru3 triangle. Each Ru atom carries one equatorial and two axial terminal carbonyl ligands. The three arsine-substituted benzene rings make dihedral angles of 82.69 (9), 70.43 (9) and 89.45 (9)° with each other. The dihedral angles between the two benzene rings are 85.14 (11) and 77.61 (10)° for the two diphenylphosphino groups. In the crystal packing, molecules are linked together into dimers via intermolecular C—H⋯O hydrogen bonds and these dimers are stacked along the a axis. Weak intermolecular C—H⋯π interactions are also present.
