    • As with all other ytterbocene polypyridyl adducts we have investigated, there are other irreversible voltammetric waves observed at potentials near the negative limit of the solvent/supporting electrolyte (∼ -3 V) that are attributed to further reductions of the bridging ligand. Likewise, oxidative electrochemistry attributed to the Cp* rings can be seen at ∼1 V in all of these systems.

    • The use of the peak current in the ligand-based oxidation wave as an internal standard in constructing Figure 3 eliminates uncertainties in complex concentration and electrode surface area, but there can still be differences in the diffusion coefficients for the oxidation versus reduction waves that could contribute to differences in the observed slopes. However, these are expected to be relatively small because both processes involve the diffusion of a neutral species of the identical hydrodynamic radius to the electrode surface
