| Summary: | The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru3(C25H22P2)(C19H17PS)(CO)9]·CH2Cl2, contains one triangulo-triruthenium complex molecule and one half-molecule of the dichloromethane solvent. The dichloromethane solvent molecule lies across a crystallographic inversion center leading to the molecule being disordered over two positions of equal occupancy. The bis(diphenylphosphanyl)methane ligand bridges an Ru—Ru bond and the monodentate phosphane ligand bonds to the third Ru atom. All phosphane ligands are equatorial with respect to the Ru3 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 87.18 (11), 59.59 (10) and 89.28 (11)° with each other. The dihedral angles between the two benzene rings are 78.48 (11) and 87.58 (11)° for the two diphenylphosphanyl groups. In the crystal, the molecules are stacked along the a axis. Weak intermolecular C—H...π interactions stabilize the crystal structure.
