[μ-Bis(di-o-tolyl-phosphan-yl)methane-1:2κP:P']nona-carbonyl-1κC,2κC,3κC-[diphen-yl(phenyl-sulfanylmeth-yl)phosphane-3κP]-triangulo-triruthenium(0) dichloro-methane 0.25-solvate.

In the title compound, [Ru(3)(C(29)H(30)P(2))(C(19)H(17)PS)(CO)(9)]·0.25CH(2)Cl(2), the atoms of the dichloro-methane solvent mol-ecule have a fractional site occupancy of 0.25; the dichloro-methane mol-ecule is disordered about an inversion centre. The bis-(di-o-tolyl-phosphan-yl)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 diphenyl-phosphanyl ligand are 68.4 (2) and 71.5 (2)°. In the crystal, mol-ecules are linked into [001] chains via inter-molecular C-H⋯O hydrogen bonds. Weak inter-molecular C-H⋯π inter-actions also occur.
