Rhodium(III) nitrate is a proposed inorganic compound 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 with similar stoichiometry are known; 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]


Rhodium(III) nitrate is used as a precursor to synthesize rhodium.[7]
