Popis: Heterodinuclear complexes of the types [(dppe)M(μ-SR)2Pd(η3-allyl)][ClO4] (M=Pd or Pt) and [(dppe)Pt(μ-SC2H4S)Pd(η3-allyl)][ClO4] [dppe=1,2-bis(diphenylphosphino)ethane; allyl=C3H5 or C4H7] have been obtained by reaction of the corresponding cis-dithiolato complexes, [M(SR)2 (dppe)] or [Pt(SC2H4S)(dppe)], and [Pd(η3-allyl)(PhCN)2][ClO4]. The identity of these complexes has been established by NMR (1H and 31P) spectroscopy. The crystal structure of [(dppe)Pd(μ-SC6H4Me-p)2Pd(η3-C3H5)][ClO4] has been determined by single-crystal X-ray methods. The p-tolyl groups on the sulfur atoms adopt a syn conformation with respect to the central PdS2Pd core.
