PH2Ph, edge-bridging PHPh and/or capping PPh ligands have been isolated from the reaction of M3(CO)12 (M = Ru or Os) with PH2Ph in refluxing solvents. HRu3(CO)10(PHPh) (IIIa) crystallises in the monoclinic space group P21/c with a = 8.761(3), b = 11.402(4), c = 22.041(7) Å,β = 98.89(2)°, and Z = 4. The structure was solved by a combination of direct methods and Fourier difference techniques, and refined
