    Resolving the Two-Electron Process for the Couple [(C5Me5)M(N^N)Cl]+/[(C5Me5)M(N^N)], (M = Rh , Ir) into Two One-Electron Steps Using the 2,2''''-Azobis(pyridine) N^N Ligand, Fast Scan Cyclovoltammetry and Spectroelectrochemistry: Detection of Radicals I

  • Original language description

    The complex cations [(C5Me5)M(abpy)Cl]+, M = Rh or Ir, abpy = 2,2''''''''azobispyridine, are reduced to the coordinatively unsaturated compounds [(C5Me5)M(abpy)] via EPR- and UV/VIS-spectroelectrochemically detectable radical intermediates [(C5Me5)MIII(abpy-I)Cl];. Fast-scan cyclic voltammetry allowed us to establish the electrochemical potentials. This stepwise mechanism differs from the two-electron processes observed for analogous systems [(C5Me5)M(N^N)Cl]+/[(C5Me5)M(N^N)] with N^N = 2,2bipyridines,bidiazines or 1,4-diaza-1,3-butadienes. In contrast to cobalt systems like [(C5Me5)Co(bpy)Cl]+ the one-electron reduction does not involve the metal. The role of the abpy ligand as intermediate one-electron storage component for a metal-centered two-electron process is discussed. Further reduction of [(C5Me5)M(abpy)] to [(C5Me5)MII(abpy-II)]- at very negative potentials illustrates the extremely strong ; back donation from the 14 valence electron fragments (C5Me5)M, M = Rh or Ir.
