In the title solvated triangulo-triruthenium compound, [Ru3(C18H15O3P)(C29H30P2)(CO)9]·2CHCl3, the bis­(di-o-tolyl­phosphan­yl)methane (dtpm) ligand bridges one of the Ru—Ru bonds and the monodentate phosphine ligand bonds to the third Ru atom. All the P atoms are equatorial with respect to the Ru3 triangle: each Ru atom also bears one equatorial and two axial terminal carbonyl ligands. The dihedral angles between the two benzene rings are 75.92 (10) and 78.95 (10)° for the two diphenyl­phosphanyl groups of the dtpm ligand. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules into chains along [010].
