Several Pd(II) and Pt(II) complexes of tripropylarsines (AsR3; R = Pr, iPr) MCl2(AsR3)2, M2Cl2(m-Cl)2(AsR3)2, Pd2Me2(m-Cl)2(AsR3)2, Pd2X2(m-Pz)2(AsR3)2 (X = Cl or Me, Pz = pyrazolate), Pd2Cl2(m-Y)2(AsR3)2 (Y = OAc or SPh), MCl(S2CNEt2)(AsR3) and PdCp(Cl)(AsiPr3) (M = Pd or Pt) were prepd. All the complexes were characterized by elemental analyses, IR and 1H NMR spectroscopy. The stereochem. of the complexes was deduced from the spectroscopic data. The structures of Pd2Me2(m-X)2(AsiPr3)2 (X = Cl or Pz) were established by single crystal x-ray diffraction analyses. Both of the complexes have sym-trans configuration. Strong trans influence of the Me group is reflected on the Pd-X bond distances. on SciFinder(R)
