Electrphilic Behaviour of Nitrosyls: Preparation and Reactions of Six-co-ordinate Ruthenium Tetra(pyridine) Nitrosyl Complexes
Reaction of NO2(1-) with gave which on treatment of HCl gave (2+) isolated as ClO4(1-) or PF6(1-) salts.Use of HBr or HClO4 instead of HCl gave (2+) or (2+) respectively.The nitrosyl ligand in (2+) behaved as an electrophile .With OH(1-) was formed reversibly.With an excess of N3(1-) and 2 a mixture of and (1+) was formed, N2 and N2O being evolved.The less soluble 2 reacted with an equimolar amount of N3(1-) to give PF6, which was unstable with respect to N2 loss in solution, and was contaminated with a small quantity of a reduced nitrosyl complex, believed to be 2 or 2*H2O.The formation of (1+) indicates that the reaction between (2+) and N3(1-) proceeds via a cyclic RuN4O intermediate, as was confirmed by labelling experiments.Electrochemical one-electron reduction of (2+) gave (2+), isolated as the PF6(1-) salt; it is not known how strongly the H2O molecule is attached to the ruthenium, if at all.Electrochemical six-electron reduction of (2+) gave (1+); this same product could be isolated as the PF6(1-) salt from zinc amalgam reduction of (2+).Polarographic, coulometric, and cyclic voltammetry experiments showed that (2+) is reduced in two successive reversible one-electron steps followed by an irreversible four-electron reduction.
