Rhodium(III) nitrate
Rhodium nitrate is an inorganic compound, a salt of rhodium and nitric acid with the formula Rh3. This anhydrous complex has been the subject of theoretical analysis but has not been isolated. However, a dihydrate and an aqueous solution are known with similar stoichiometry; they contain various hexacoordinated rhodium aqua and nitrate complexes. A number of other rhodium nitrates have been characterized by X-ray crystallography: Rb4 and Cs2. Rhodium nitrates are of interest because nuclear wastes, which contain rhodium, are recycled by dissolution in nitric acid.
