Rhodium(III) nitrate

Rhodium(III) nitrate is an inorganic compound, a salt of rhodium and nitric acid with the formula Rh(NO₃)₃. This anhydrous complex has been the subject of theoretical analysis but has not been isolated.^[4] However, a dihydrate and an aqueous solution are known with similar stoichiometry; they contain various hexacoordinated rhodium(III) aqua and nitrate complexes.^[3] A number of other rhodium nitrates have been characterized by X-ray crystallography: Rb₄[trans-[Rh(H₂O)₂(NO₃)₄][Rh(NO₃)₆]^[4] and Cs₂[-[Rh(NO₃)₅].^[5] Rhodium nitrates are of interest because nuclear wastes, which contain rhodium, are recycled by dissolution in nitric acid.^[6]
