• Associated context:

  As shown in Figure 3A, compound 3 displays a single unresolved redox couple for the two ferrocenes, which means that the redox potentials of these two moieties must be within a few tens of millivolts of one another.33 Viewed another way,  as previously determined for 43,6 the unsymmetric 2,5-diethyl-nylpyridyl unit of 3 is sufficiently long enough so that the two ferrocene groups of 3 do not experience any significant electrostatic repulsion between one another upon oxidation,34 nor does the unsymmetric nature of this bridging group preferentially perturb the electronic structure of one ferrocene significantly over the other.
