a

ΔEp(Fc0/+) = 0.064 V under these conditions.

b

Anodic potential for irreversible oxidation.

c

Data from ref (15).

d

Calculated and experimental values for [1′]BF4 agree by construction and were used as references for the corresponding [1] waves.

e

Calculated and experimental values for [2′]BF4 agree by construction and were used as references for the corresponding [2], [3], and [3′] waves.

f

This value was not determined as difficulties arising from local minima led to inconclusive results.

g

This wave is assigned to a Fe0PtII/FeIPtII couple (vide infra).
