Heteroleptic palladium(II) and platinum(II) complexes of 1,1-bis(diphenylphosphino)ferrocene (dppf) and heterocyclic thionates: Crystal structures of [Pt(Phozt) _2(κ ~2-dppf)] (PhoztH = 5-phenyl-1,3,4-oxadiazole-2-thione) and [Pd(bzoxt) _2(κ ~2-dppf)] (bzoxtH = benz-1,3-oxazoline-2-thione)

摘要

Treatment of [MCl _2(κ ~2-dppf)] (M = Pd or Pt) with two equivalents of potassium heterocyclic thionate salts (KL) affords mixed ligand complexes [ML _2(κ ~2-dppf)] [L = 5-phenyl-1,3,4-oxadiazole-2-thionate (Phozt), 4,5-diphenyl-1,2,4-triazole-3- thionate (Ph _2tzt), benz-1,3-thiazoline-2-thionate (bztzt) and benz-1,3-oxazoline-2-thionate (bzoxt)]. X-ray structures of two examples, [Pt(Phozt) _2(κ ~2-dppf)] and [Pd(bzoxt) 2(κ 2-dppf)], show that the ligands are coordinated in a monodentate fashion via the sulfur atom.
