The Lever parameter ( E L), for a series of ruthenium nitrosyl complexes of the type [Ru(NH3)4NOL] n+, where ligand L = nicotinamide (nic), isonicotinamide (isn), pyrazine (pz), pyridine (py), imidazole (imN), L-histidine (L-hist), NH3, trimethyl phosphite [P(OMe)3] and triethyl phosphite [P(OEt)3], is correlated to Epc1 (the potential for the reduction RuNO++e- ? RuNO 0) and v (NO) data. A correlation is observed between ? E L and E pc1, and between ? E L and v (NO), since these parameters are dependent on electronic characteristics of the nitrosyl group. For ? E L v. Epc1, the slope, S L, and intercept, I L, of the linear correlation are related to interligand coupling through the metal centre and to the extent of the Ru ? NO back bonding.
