The compounds [(AuCl)2(μ-dppr)] (dppr = 1,1’-bis(diphenylphosphino)ruthenocene) and [(AuCl)2(μ-dppo)] (dppo = 1,1’-bis(diphenylphosphino)osmocene) were prepared by the reaction of [Au(SMe2)Cl] with the appropriate phosphine to give the desired compounds in good yield. The new compounds were fully characterized by NMR. The X-ray crystal structures of both compounds were determined. The compounds adopt the P21/n space group and display parameters similar to the dppf (dppf = 1,1’-bis(diphenylphosphino)ferrocene) analog. The %Vbur for dppr and dppo in these compounds was calculated. In addition, the oxidative electrochemistry of these compounds was examined in methylene chloride.
