Abstract:The title compound, P (CH2Ph) Ph3] PdWS4(S2CNC4H8)], wassynthesized by ligand replacement reaction of Pd(S2CNC4H8)2 with (NH4)2WS4 in thepresence of P(CH2Ph)Ph3]Cl in CH2Cl2 and characterized by X-ray diffraction analy-ses. Crystallographic data: triclinic, observed reflections with . The crys-tal contains discrete cations and anions. Palladium atom in the anion is coordinated by apyrrolidine-derived dithiocarbamate and a tetrathiotungstate. Both dithiocarbamate andtetrathiotungstate act as bidentate ligands through two sulfur atoms chelating palladiumatom. The Pd-W distance is 2- 847(1).
Keywords:synthesis  crystal structure  dithiocarbamate  palladium-tungsten-sulfur
