Abstract

The neutral complexes [{M(μ-SPPh₂)(C₆F₅)(PR₃)} ₂] (M = Pd or Pt; PR₃ = PPh₃ or PPh₂Et) containing the P,S-bridging [SPPh₂]^- have been synthesised by reaction of the corresponding acetylacetonate (acac) derivatives [M(C₆F₅)(acac-O,O′)(PR₃)] with HP(S)Ph₂. However, the reaction of the cationic complexes [M(acac-O,O′)(PPh₃)₂]ClO₄ (M = Pd or Pt) with HP(S)Ph₂ affords mononuclear [M(SPPh₂)(PPh₃)₂]ClO₄ in which the [SPPh₂]^- ligand is co-ordinated as a P,S-chelate. The anionic complex [NBu₄]₂[{Pd(μ-SPPh₂)(C₆F ₅)₂}₂] has also been synthesised. The crystal structures of [{Pd(μ-SPPh₂)(C₆F₅)(PPh₃)} ₂] and [Pd(SPPh₂)(PPh₃)₂]ClO ₄·CH₂Cl₂ have been determined by X-ray diffraction methods; the former adopts a boat conformation.
