Long-range coupling in a mixed-valence diruthenium complexes containing bis-terpyridine ligands of various lengths as bridges

Abstract

Dinuclear ruthenium(II) complexes have been prepared which contain back-to-back bis-terpyridine ligands of various lengths (Ru ⋯ Ru distances between 7 and 20 Å) as bridges; significant electronic coupling is observed in mixed-valence states, even for the system with the longest separation.
