Abstract
[MX2L2] (M = Pd, Pt; L = di(1-naphthyl)methylarsine = Nap2AsMe and X = Cl, Br, I), [M2Cl2(m-Cl)2L2], [PdCl(S2CNEt2)L], [Pd2Cl2(m-OAc)2L2] and [MCl2(PR3)L] (PR3 = PEt3, PPr3, PBu3, PMePh2) were prepd. These complexes were characterized by elemental analyses, IR, Raman, NMR (1H, 13C, 31P) and UV-visible spectroscopy. The stereochem. of the complexes was deduced from the spectroscopic data. The crystal structures of trans-[PdCl2(PEt3)(Nap2AsMe)] and of [Pd(S2CNEt2)2], a follow-up product, were detd. The UV-visible spectra of [MX2L2] complexes show a red shift on going from X = Cl to X = I. [PdX2L2] and [PtX2L2] are strongly luminescent in fluid soln. and in the solid at ambient temp.
