  Unprecedented formation of selenido-bridged tri-nuclear palladium(II) and platinum(II) complexes, [M3(μ3-Se)2(P∩P)3]2+, via C–Se bond cleavage

  摘要：

  Reaction of [M(SeCOC6H4Me-4)(2)((PP)-P-boolean AND)] with MCl2((PP)-P-boolean AND) in the presence of NaBPh4 in dichloromethane-methanol mixture afforded selenido-bridged tri-nuclear complexes [M-3(mu(3)-Se)(2)((PP)-P-boolean AND)(3)][BPh4](2) (M-3 = Pd-3, Pt-3, Pd2Pt, PdPt2; (PP)-P-boolean AND = dppm, dppe, dppp, ((PPr3)-Pr-n)(2)) formed via unprecedented cleavage of C-Se linkage of selenocarboxylate. These complexes were characterized by UV-Vis and NMR (H-1, P-31, Se-77, Pt-195) spectroscopy. The structure of [Pd-3(mu(3)-Se)(2)(dppe)(3)][BPh4](2) was established by X-ray crystallography. The geometry around each palladium atom is approximately square planar with two P atoms from the chelating dppe and two Se atoms defining the coordination sphere. (C) 2006 Elsevier Ltd.

  Palladium(II) and platinum(II) monoselenocarboxylates: Synthesis, spectroscopy, structure and their use as molecular precursors for metal selenides

  摘要：

  Treatment of MCl2((PP)-P-boolean AND) or MCl2((PPr3)-Pr-n)(2) With two equivalents of ArCOSeK readily yields cis-[M(SeCOAr)(2)((PP)-P-boolean AND)] and trans[M(SeCOAr)(2)((PPr3)-Pr-n)(2)], respectively (M = Pd or Pt; Ar = Ph or 4-MeC6H4; (PP)-P-boolean AND = dppm, dppe, dppp). The reaction of Pd(SeCOAr)(2)(dppe) with PdCl2(dppe) in the presence of NaBPh4 in methanol gave a tri-nuclear ionic complex, [Pd-3(mu(3)-Se)(2)(dppe)(3)][BPh4](2). These complexes were characterized by UV-Vis, IR and NMR spectroscopy. The complex [Pt(SeCOPh)(2)(dppp)] has been structurally characterized by X-ray crystallography. The coordination environment around square planar platinum atom is defined by chelating dppp ligand and two unidentate selenocarboxylates bonded through selenium atoms. Pyrolysis of [Pd(SeCOAr)(2)((PPr3)-Pr-n)(2)] either in tri-n-butylphosphate (TBP) (at 200 degrees C) or in the solid state (furnace heating at 350 degrees C) gave Pd17Se15. (c) 2005 Elsevier B.V.
