In the title compound, [Ru3(C6H12Cl3O3P)(C29H30P2)(CO)9], the bis­(di-o-tolyl­phosphan­yl)methane ligand bridges one Ru—Ru bond and the monodentate phosphite ligand bonds to the third Ru atom. Both ligands are equatorial with respect to the Ru3 triangle. Each Ru atom bears one equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings in the diphenyl­phosphanyl groups are 79.52 (10) and 69.88 (10)°. In the crystal, mol­ecules are linked via C—H⋯O hydrogen bonds into chains along [100].
