ResumoVariable temperature 19F and 31P n.m.r. studies of some tris(pentafluorophenyl)phosphine platinum complexes show restricted rotation at low temperatures about the Pt–P and C(1)–P bonds with a preferred conformation in which none of the C(1)–P bonds lie in the platinum co-ordination plane; the mechanism of helicity reversal of the propeller-shaped ligand is a two-ring flip.
