Resumen:
A series of cyanide-bridged bimetallic compounds of the general formula [Ru(L)(bpy)(µ-NC)(M)]2-/-/2+ (L = tpy, 2,2-6,2-terpyridine, or tpm, tris(1-pyrazolil)methane, bpy = 2,2-bipyridine, M = RuII(CN)5, OsIII(CN)5, OsII(CN)5, RuII(py)4(CN), py = pyridine) have been synthesized and fully characterized. All of them present MLCT emission (λ = 690-730 nm, Φ = 10-3-10-4) and their photophysical properties resemble the ones of the respective mononuclear Ru(L)(bpy) species, except when M is OsIII(CN)5, where an intramolecular electron transfer quenching mechanism is proposed. In addition, all the structures present exposed cyanide groups which may be used to prepare systems of higher nuclearity.
