Bis{[μ-bis(diphenylphosphanyl)methane-1:2κ2P:P′]nonacarbonyl-1κ3C,2κ3C,3κ3C-[(4-methylsulfanylphenyl)diphenylphosphane-3κP]-triangulo-triruthenium(0)} dichloromethane monosolvate

Abstract

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.
