Complexes >^- (1), > (2) and >⁺ (3) have been synthesized by the reaction of with S2C2(CN)2^2- or >⁺ when further reacted with formed a dinuclear complex >²⁺ (4).All these complexes have been characterized by their physical and spectral (IR; 1H 31P NMR and visible spectra) data.S2C2(CN)2^2- has been found to introduce a low lying MLCTabsorption in the electronic spectra of its complexes.In CV scan these complexes exhibit an extended series of one electron transfer reactions.The metal-centred oxidation waves of the complexes have been correlated with the ? acidity of ligands.Keywords: Cyclopentadienyl; Dithioether; Electrochemistry; Maleonitriledithiolate; Ruthenium; Visible spectra
