Copper peroxide is a hypothetical inorganic compound with the chemical formula Cu O2. The 1:2 ratio of copper and oxygen would be consistent with copper in its common +2 oxidation state and a peroxide group. Although samples of this composition have not been isolated, CuO2 has attracted interest from computational perspective. One highly cited analysis concludes that gaseous CuO2 is a superoxide, with copper in a +1 oxidation state: Cu+O−2. [1]
Species claimed to be "copper peroxide" have been claimed, e.g., by the reaction of cold solutions of Schweizer's reagent—a source of copper(II)—and hydrogen peroxide.. [2] The Schweizer's reagent used must not contain excess ammonia. [2]
It was once claimed to result from the very slow reaction of finely divided cupric oxide with cold hydrogen peroxide. [3]
Several molecular copper peroxide complexes have been reported, but these species always feature supporting organic ligands. [4]
