The reaction of Pt(SiHPh2)2(dmpe) (dmpe = 1,2-bis(dimethylphosphino)ethane) with Pd(PCy3)2 forms (Cy3P)Pd(μ-η2-HSiPh2)2Pt(PCy3) (1), which contains two diphenylsilyl ligands bridged to Pd and Pt centers. A comparison of the crystallographic results and the NMR spectra of 1 with those of [(Cy3P)Pd(μ-η2-HSiPh2)]2 (3) and [(Cy3P)Pt(μ-η2-HSiPh2)]2 (4) indicates that the structure of 1 contains two inequivalent
