Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Dissociation energies, Δ<italic>U</italic>_diss, of dimeric </bold> organometallic n‐dopants affect the thermodynamics and kinetics of their redox reactions. Although the bond lengths in dimers of organic radicals decrease with increasing Δ<italic>U</italic>_diss, this is not the case for the present dimers; instead, trends in stability of Δ<italic>U</italic>_diss correlate with those in the stability of the 19‐elecron monomers. The HOMOs and X‐ray structures of [RuCp*(C₆H₃Et₃)]₂ and [FeCp*(C₆H₆)]₂ are shown; DFT calculations indicated a significantly larger Δ<italic>U</italic>_diss for the former, yet X‐ray (and DFT) showed a slightly longer bond.
