Abstract Four ditopic bridging ligands, containing 2, 2′: 6′, 2′′-terpyridine and 2, 6- dipyrazinylpyridine (dpp) metal-binding units attached through p-or m-phenylene linkages, have been incorporated into eight mono-, di-and trinuclear linear Ru II complexes. These were characterized by UV/Vis spectroscopy and cyclic voltammetry, and by their ability to undergo light-induced electron transfers to methylviologen. The dpp-bearing complexes ...
