Abstract

New ruthenium(III) complexes trans-[NBu4][RuX4(CNTM)(2)] (X = Cl or Br, CNTM = p-tolylsulfonylmethylisocyanide) have been prepared by treating [NBu4](2)[RuX6] with the isocyanide ligand CNTM in EtOH-CH2Cl2 solution. In situ IR and UV-Vis spectroelectrochemical studies have shown that reduction of trans-[RuX4(CNTM)(2)](-) in acetonitrile and subsequent oxidation yields mer,trans-[RuX3(CNTM)(2)(NCMe)]. Similar studies have shown, interestingly, that oxidation of trans- [RuX4(CNTM)(2)](-) and subsequent reduction also yields the same product. Differences between the redox behaviour of trans- [RuX4(CNTM)(2)](-) and trans-[RuX4((CNBu)-Bu-t)(2)](-) (X = Cl or Br, (CNBu)-Bu-t = tert-butylisocyanide) in the presence of free isocyanide ligand have also been identified.
