Bis(bidentate) complexes of iminobis(diphenylphosphine chalcogenides)[M{N(XPPh2)2-X,X′}2](X = S or Se; M = Ni, Pd or Pt)

Abstract

The compound NH(SePPh2)2 has been synthesised from NH(PPh2)2 and selenium in refluxing toluene. A range of complexes [M{N(XPPh2)2-X, X′}2](X = Se, M = Pt 1 or Pd 2; X = S, M = Pt 3, Pd 4 or Ni 5) of the monoanions derived from NH(SePPh2)2 and its sulfur analogue have been prepared. The new compounds have been characterised by microanalysis, NMR and IR spectroscopy. The crystal structures of NH(SePPh2)2, 1, 2 and 5 were determined. The neutral NH(SePPh2)2 crystallised as H-bonded dimer pairs with a noticeable difference in the hydrogen bonded and non-hydrogen bonded P[double bond, length half m-dash]Se bond lengths. The P[double bond, length half m-dash]Se groups are approximately anti. On complexation the anionic ligands are bidentate and in all cases the resulting MX2P2N rings are distinctly puckered.
