Abstract

A series of trans-RuL­(PPh3)2(nitrile) and {RuL­(PPh3)2}.2-μ-(nitrile)-based complexes [where L = 2,2′-(3,4-diphenyl-pyrrole-2,5-diyl)­dipyridine (dpp), di­(pyridin-2-yl)­isoindoline-1,3-diimine (bpi), or 4-(4-methoxyphenyl)-6-phenyl-2,2′-bipyridine (Pbpy); and nitrile = 1,4-dibenzontirile, 4-ethynylbenzonitrile, or dicyanamide] were synthesized and characterized, and their electrochemical and photochemical behaviors were investigated. Those complexes that contained a significant nitrile contribution to their 3MLLCT show a release of their nitrile ligand (when L = dpp or Pbpy and the nitrile ligand = 4-dibenzontirile, or 4-ethynylbenzonitrile) with dissociation constants up to 8.09 × 10–4 s–1.
