    • note
    • The paramagnetic contribution of the unpaired electron to the relaxation rates of the protons is negligibly small for those in the fc unit (Fe(II), S = 0) compared with those in the ferrocenium unit (Fe(III), S = 1/2), because the proton relaxation rates, caused by the dipolar interaction with the electron spin or by the hyperfine interaction, depend, respectively, on the - 6th powers of the distance between the proton and the electron spin or on the magnitude of the hyperfine parameter.

    • These relations are also satisfied at the other temperatures and in the other solvents used in ref 16. The experimental conditions in ref 16 almost cover those in the present study.

    • IS = 2.85 Å, θ = 53.9°) were used for the all of the mixed-valence monocations in the present study because a variation in the distance and the angle in each mixed-valence monocation caused by the crystal packing or the counteranion is similar to or even exceeds that by difference in the substituents on the cp rings.

    • -1, corresponds to the 0-intercept in the Pekar plot because the solvent dependences of the values are negligible. The estimated value is similar to those experimentally obtained.
