A route to homonuclear Pt3 and heteronuclear Pt2M complexes
Abstract
The complex [Pt2(µ-S)(µ-dppm)(σ-dppm)2](dppm = Ph2PCH2PPh2) prepared by reaction of [Pt2(µ-dppm)3] with COS, acts as a tridentate (P2S donor) ligand for square planar metal atoms and hence gives homonuclear (Pt3) or heteronuclear (Pt2M, M = Pd, Rh, or Ir) complexes, which show unusual fluxional behaviour involving sulphur inversion.
