Nickel(III) oxide is the inorganic compound with the formula Ni2O3. It is not well characterised,[1] sometimes referred to as black nickel oxide. Traces of Ni2O3 on nickel surfaces have been mentioned.[2][3] A related, better characterized material is nickel oxide hydroxide (NiOOH), which is likely the reagent employed in organic synthesis since it is generated in aqueous media.
