Fig. 3. (a) Cyclic voltammograms in CPE cell. [CoLDMA(CH3CN)2][BF4]2 in 5 : 95 H2O/CH3CN (red), [CoLDMA(CH3CN)2][BF4]2 in 0 : 100 H2O/CH3CN (blue), and no catalyst present under the same conditions (gray and black). (b) Charge passed vs. time in the controlled potential electrolysis of a 1 mM solution of [CoLDMA(CH3CN)2][BF4]2 (2) in 95 : 5 CH3CN : H2O (v/v) at 1.07 V vs. Fe(C5H5)2+/0 (red trace). Equivalent electrolyses under the same conditions; [CoLH(CH3CN)2][BF4]2 (1, green trace), [Co(CH3CN)6][BF4]2 (lavender trace), and rinsed post-electrolysis electrode in fresh Bu4NPF6 solution (black trace).
