29. 3+ could also account for the depleted reduction peak in 1. Such short-cut reactions between the mixed-valence states (Scheme 1) have been reported for similar systems (see, e.g., Harman, W. D.; Taube, H. J. Am. Chem. Soc. 1988, 110, 5403-5407.
30. Sano, M.; Sago, H.; Tomita, A. Bull. Chem. Soc. Jpn. 1996, 69, 977-981). The analogous behavior of equimolar mixtures of 2b and 3 and the better agreement of isomerization parameters for 1 and 2b (Supporting Information) indicate, however, that the voltammograms of complex 1 are more readily rationalized on the basis of the comproportionation reaction (eq 1).
