Intramolecular Electron-Transfer Across Polyenebridges
The new bipyridylpolyene bridged bimetallic complexes [{LMo(NO)Cl}NC5H5-(C2H2)n-C5H5N] (n = 2-4 all trans) have been synthesised along with their monometallic counterpart [{LMo(NO)Cl}NC5H5-(C2H2)n-C5H5N]. All of the bimetallic complexes exhibit EPR spectra consistent with fast electron exchange between the metal centres and may be reduced in two 1-electron processes, the separation between which decreases by approximately 166 mV per additional ethenyl unit.
