Abstract:The reactions of dirhodium(II) aquo cation {Rh2(aq)4+} with dioxygen were examined. It has been found that the nature of the oxidation product depends upon the concentration of dioxygen in the solution. The dimeric or polymeric Rh(III)(aq) cationic species with a charge of greater than +3 is formed when air oxygen slowly diffuses into a solution containing Rh2(aq)4+. The paramagnetic cation of proposed formula (H2O)4Rh(O2)(OH)2Rh(H2O)4]3+ is formed when molecular oxygen is bubbled through a 2–3 M HClO4 solution of Rh2(aq)4+. This species has been isolated and characterized in solution.
