[μ-Bis(di-o-tolylphosphanyl)methane-1:2κ2P:P′]nonacarbonyl-1κ3C,2κ3C,3κ3C-[diphenyl(phenylsulfanylmethyl)phosphane-3κP]-triangulo-triruthenium(0) dichloromethane 0.25-solvate

In the title compound, [Ru-3(C29H30P2)(C19H17PS)(CO)(9)]center dot-0.25CH(2)Cl(2), the atoms of the dichloromethane solvent molecule have a fractional site occupancy of 0.25; the dichloromethane molecule is disordered about an inversion centre. The bis(di-o-tolylphosphanyl) methane ligand bridges an Ru-Ru bond and the monodentate phosphane ligand bonds to the third Ru atom; its S-bonded phenyl ring is disordered over two orientations in a 0.53 (4): 0.47 (4) ratio. All the P atoms are equatorial with respect to the Ru-3 triangle: each Ru atom also bears one equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings attached to each P atom of the diphenylphosphanyl ligand are 68.4 (2) and 71.5 (2)degrees. In the crystal, molecules are linked into [001] chains via intermolecular C-H center dot center dot center dot O hydrogen bonds. Weak intermolecular C-H center dot center dot center dot pi interactions also occur.
