摘要: Abstract The late transition metal complexes [(Ar)RuCl2(PS)] (Ar=C6H6, o-MeC6H4(iPr) and C6Me6), [RuCl2(η3:η3-C10H16)(PS)], [RhCl(cod)(PS)] (cod=1,5-cyclooctadiene) [(Cp*)MCl2(PS)] (Cp*=pentamethylcyclopentadienyl, M=Rh or Ir) (where PS=Ph2PNHC6H4P(S)Ph2) have been synthesised by the reaction of Ph2PNHC6H4P(S)Ph2 with appropriate chloride bridged dimers. In all these ligand is monodentate P-bound. Chloride abstraction from representative complexes, using Ag[ClO4], gave cationic compounds [(o-MeC6H4{iPr})RuCl(PS)][ClO4], [Rh(cod)(PS)][ClO4] [(Cp*)RhCl(PS)][ClO4] in which k2-P,S bound. All new were characterised a combination 31P{1H} 1H NMR spectroscopy, microanalysis, FAB mass spectrometry IR spectroscopy. molecular structures five determined single-crystal X-ray diffraction—both chelate coordination has characterised. P-monodentate display intramolecular NH⋯S hydrogen bonding.
