The crystal structures of dppf [dppf=1,1′-bis(diphenylphoshino)ferrocene] and (dppf)NiCl2 were determined by X-ray crystallography and refined toR=0.043 (both). The molecule of dppf is centrosymmetric, with the inversion center at the Fe atom. The ferrocene rings are parallel and staggered. In (dppf)NiCl2 the coordination around nickel is tetrahedral, with a significantly large Cl-Ni-Cl angle (125°) due to repulsion of the chlorine atoms. The ferrocene ligand exhibits a slightly distorted (9… Expand
