Treatment of [MCl2(kappa(2)-dppf)] (M = Pd or Pt) with two equivalents of potassium heterocyclic thionate salts (KL) affords mixed ligand complexes [ML2(kappa(2)-dppf)] [L = 5-phenyl-1,3,4-oxadiazole-2-thionate (Phozt), 4,5-diphenyl-1,2,4-triazole-3-thionate (Ph(2)tzt), benz-1,3-thiazoline-2-thionate (bztzt) and benz-1,3-oxazoline-2-thionate (bzoxt)]. X-ray structures of two examples, [Pt(Phozt)(2)(kappa(2)-dppf)] and [Pd(bzoxt)(2)(kappa(2)-dppf)], show that the ligands are coordinated in a monodentate fashion via the sulfur atom.
