  The syntheses, 31P{1H} NMR spectra and cyclic voltammetry of trinuclear [Pd2M(μ3-Se)2(dppe)3]2+ {M=Ni or Pt; dppe=1,2-bis(diphenylphoshino)ethane} and pentanuclear [M′{Pd2(μ3-Se)2(dppe)2}2]2+ (M′=Ni, Pd or Pt) clusters with selenido bridges

  摘要：

  Trinuclear [Pd2M(mu (3)-Se)(2)(dppe)(3)](2+) (M = Ni or Pt) and pentanuclear [M ' {Pd-2(mu (3)-Se)(2)(dppe)(2)}(2)](2+) (M' = Ni, Pd or Pt) clusters have been prepared using a metalloligand [Pd-2(mu -Se)(2)(dppe)(2)] and characterized by P-31{H-1} NMR spectroscopy and cyclic voltammetry. [Pd2Ni(mu (3)-Se)(2)(dppe)(3)](2+) gives two chemically reversible couples, [Pd2Pt(mu (3)-Se)(2)(dppe)(3)](2+) exhibits one chemically reversible couple and pentanuclear clusters show three couples in each cyclic voltammogram of the reduction process at 255 K. The redox behavior of the clusters is discussed. (C) 2001 Elsevier Science B.V. All rights reserved.

  The reactions of [M(dppe)2] (M=Pd, Pt) with elemental selenium or tellurium: preparation and structure of the platinum polyselenide [PtSe4(dppe)]

  摘要：

  Reaction of [Pt(dppe)(2)] (dppe = 1,2-bis(diphenylphosphino)ethane) with elemental selenium in toluene under reflux, or of [PtCl2(dppe)] with lithium polyselenide in tetrahydrofuran, leads in good yield to the complex [PtSe4(dppe)] whose structure has been determined by X-ray crystallography. Reaction of [Pt(dppe)(2)] with elemental tellurium, followed by treatment with dichloromethane, leads to isolation of the salt [Pt-3(mu(3)-Te)(2)(dppe)(3)] Cl-2. [Pd(dppe)(2)] reacts with elemental selenium to give [Pd-2(mu-Se)(2)(dppe)(2)] or [Pd-3(mu(3)-Se)(2)(dppe)(3)] Cl-2, depending on the conditions. (C) 2000 Elsevier Science Ltd All rights reserved.
