Summary
Palladium(II) halides react with triphenylphosphine sulphide or selenide, 1,1-methylenebis(diphenylphosphine sulphide or selenide) (MDPS or MDPSe), 1,3-trimethylene-bis-(diphenylphosphine selenide) (PDPSe) or tetramethyldiphosphine disulphide (TMDPS) forming complexes [PdBr2 · 2L], [2PdBr2 · 3L] (L=Ph3PS or Ph3PSe), [PdX2 · L] (X=Cl, L =PDPSe; X=Br, L=MDPS or MDPSe; X=Cl or Br, L=TMDPS) and [3PdBr2 · 2TMDPS]. Characterisation and stereochemical assignments have been made through elemental analyses, i.r., far i.r. and electronic spectra, magnetic susceptibility and molar conductance data and tga studies. Bidentate ligand complexes have higher thermal stability than the monodentate ligand complexes. Chelation or bridging modes of the bidentate ligands have been demonstrated.
