Effect of ligand exchange on the one-electron oxidation process of alkoxo or phenoxo bridged binuclear copper(II) complexes

•Two different dicopper(II,II) complexes were prepared.•Binding of methoxide/methanol and replacement of the existing bridges was investigated.•The redox properties were mesures and compared to the computed values.•The nature of the one-electron oxidized species was investigated by DFT calculations.
