Theoretical calculations on tris(4-trifluoromethyltetrafluorophenyl)phosphine, 1, and spectroscopic studies of its complexes, trans-[PtCl2{P(C6F4CF3-4)3}2], 3, and trans-[RhCl(CO){P(C6F4CF3-4)3}2], 4, indicate that it is a poorer σ donor than tris(pentafluorophenyl)phosphine. The structures of 1, 3 and 4 have been determined by single crystal X-ray diffraction, and indicate that the cone angle of 1 is the same as that of tris(pentafluorophenyl)phosphine.
