Abstract: The title compound, cis-[W(CO)₂(dppe)₂] [dppe is 1,2-ethanediylbis(diphenylphosphine), C₂₆H₂₄P₂], was obtained as a by-product during the preparation of the dinitrogen complex trans-[W(CO)(N₂)(dppe)₂]. The crystal structure of the benzene sesquisolvate, i.e. cis-[W(C₂₆H₂₄P₂)₂(CO)₂]·1.5C₆H₆, has been determined.
