Electrochemical reduction of di-, tri-, tetra-, and hexanuclear complexes [Run(bpy)n+2(μ-2,X-dpp)n-1]2n+ (n = 2, 3, 4, 6; X = 3 or 5) has been studied and the reduction pattern established. It has been shown that these complexes are reduced in sequences of ligand-localized one-electron-transfer steps, organized in six multiplets of closely spaced reductions. Although the number of electron-transfer steps in each multiplet increases with increasing nuclearity, the general reduction pattern is the same for all the complexes investigated.

Abstract
Electrochemical reduction of di-, tri-, tetra-, and hexanuclear complexes [Run(bpy)n+2(μ-2,X-dpp)n-1]2n+ (n = 2, 3, 4, 6; X = 3 or 5) has been studied and the reduction pattern established. It has been shown that these complexes are reduced in sequences of ligand-localized one-electron-transfer steps, organized in six multiplets of closely spaced reductions. Although the number of electron-transfer steps in each multiplet increases with increasing nuclearity, the general reduction pattern is the same for all the complexes investigated.
