ABSTRACT: The asymmetric unit of the title compound, [Ru3(C19H17P)(C25H22P2)(CO)9], consists of two independent mol-ecules. The bis-(di-phenyl-phosphan-yl)methane ligand bridges an Ru-Ru bond and the benzyl-diphenyl-phosphane ligand binds to the third Ru atom. The Ru-Ru bond cis to the benzyl-diphenyl-phosphane ligand is the longest of the three Ru-Ru bonds in both mol-ecules. In the crystal, mol-ecules are linked by C-H?O hydrogen bonds, forming layers parallel to the ac plane. C-H?? contacts further stabilize the crystal packing.
