Abstract

Abstract: The series of nitrosyl complexes trans-[Ru(NH3)4L(NO)]Cl3, L=caffeine, theophylline, imidazole and benzoimidazole in position trans to NO were prepared and their photochemical properties studied. All complexes showed nitric oxide (NO) release under light irradiation at 330–440nm. Quantum yields for [Ru(NH3)4L(H2O)]3+ formation (ϕ Ru(III)) were sensitive to the natures of L, λ irr and pH. The major product of the irradiation of trans-[Ru(NH3)4L(NO+)]3+ is the trans-[RuIII(NH3)4L(Cl)]2+ and NO as suggested by UV–Vis, electrochemical, and FTIR techniques. [Copyright &y& Elsevier]
