“…Interestingly, the peak potential of 5 is 40 mV more cathodic than that of 4, which indicates that the electronic releasing effect of the ferrocenyl fragments on the sandwich iron center is somewhat greater than that of the mesityl subunit. Additionally, the cyclovoltammogram of compound 6 exhibited the irreversible reduction wave of the [Cp * Ru(g 6 -mesityl)] + entity, at a very negative potential (E pc = À2.29 V), more cathodic than that of the iron mixed sandwich terminus [42,43].…”

“…The compounds 3-5 show one irreversible oxidation wave in their cyclovoltammograms, whereas the heterobinuclear hydrazone 6 exhibits two irreversible oxidation processes, the most anodic one being attributed to the Ru(II)/Ru(III) couple [42,43]. The potential values listed in Table 2 are in agreement with those previously reported for methylated derivatives, ½Cp 0 Feðg 6 -C 6 Me 5Àn H n NHR 0 Þ þ PF À 6 (Cp 0 = Cp, Cp * ; R 0 = H, n-Pr; n = 0, 4) [11].…”

Slipped μ‐Indenyl Triple‐Decker Complexes Containing (C4Me4)Co and (C5R5)Ru Fragments

“…Such an assumption is supported by a comparison between the redox behaviour of ruthenocene and the benzene complex [CpRu(C 6 . The arene complex is reduced at -2.02 V but not oxidized up to +2.5 V, [28] whereas ruthenocene is oxidized at +0.8 V, [19] but, to the best of our knowledge, is not reduced up to -2 V.…”
