Mixed‐Valence States Stabilized by Proton Transfer in a Hydrogen‐Bonded Biimidazolate Rhenium Dimer

Abstract

Di-Re straits: Synchronized motion of protons and electrons, as shown in the scheme, has been observed in a hydrogen-bonded Re dimer complex. The mixed-valence states obtained by electrochemical redox reactions are stabilized by proton transfer within the dual hydrogen-bonding site between 2,2′-biimidazolate ligands.
