Abstract A novel mode of storing and releasing electrons, based on the reversible formation and cleavage of C− C bonds, has been created. The C− C bonds formed by the reductive coupling of imino groups across two [M (salophen)] complexes (see structure) function as shuttle for two electrons, permitting long-range electron transfer to a variety of substrates (eg quinone, dioxygen, and azides). This electron transfer is mediated by the metal, which ...
