Abstract: trans-[WCl₂(dppe)₂] [dppe is ethane-1,2-diylbis(diphenylphosphine), C₂₆H₂₄P₂] was formed as by-product in the reaction of trans-[W(dppe)₂(N₂)₂] with the m-terphenyltin(II) chloride, [Sn(Cl)(C₆H₃-2,6-Mes₂)]₂ (Mes is 2,4,6-trimethylphenyl), which yields mainly the stannylidyne complex trans-[Cl(dppe)₂WSn-C₆H₃-2,6-Mes₂]. The crystal structure of the pentane hemisolvate, trans-[WCl₂(dppe)₂]·0.5C₅H₁₂, has been determined. The geometric parameters of the title compound are compared with those of trans-[MoCl₂(dppe)₂]·0.5C₅H₁₂.
