Abstract

Benzyldimethylarsine complexes of Pd(II) and Pt(II) MX2(BzAsMe2)2 (X = Cl, Br, I), M2Cl2(m-Cl)2(BzAsMe2)2, Pd2Cl2(m-OAc)2(BzAsMe2)2, Pd2Me2(m-Cl)2(BzAsMe2)2 and Pd2X2(m-N-N)2(BzAsMe2)2 (M = Pd or Pt; N-N = pyrazolate (pz) or 3,5-dimethylpyrazolate (dmpz)) were prepd. All complexes were characterized by elemental anal., IR, UV-visible absorption and NMR (1H, 13C, 195Pt) spectroscopy. The mol. structures of MX2(BzAsMe2)2 (M = Pt or Pd; X = Cl, Br or I) were established by NMR spectroscopy and single crystal x-ray diffraction anal. and reveal a clear dichotomy in soln. and in the solid between the compds. with X = Cl in a cis configuration and the trans configured bromide and iodide complexes. on SciFinder(R)
