Our group has been interested in ligand-bridged, ruthenium metal complexes for several years. Recently, we have turned our attention to the synthesis of the dimer trans-trans-[PhCC-(dppm)2Ru-pyrazine-Ru(dppm)2-CCPh] where dppm = bis(diphenylphosphino)methane. We are interested in exploring the metal-metal coupling in this complex and any intervalence charge transfer bands that may exist in the partially oxidized, mixed-valent form of the dimer.  Our efforts to synthesize and characterize this complex will be presented.
