Rhodium(III) nitrate explained
Rhodium(III) nitrate is a 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. However, a dihydrate and an aqueous solution are known with similar stoichiometry; they contain various hexacoordinated rhodium(III) aqua and nitrate complexes. A number of other rhodium nitrates have been characterized by X-ray crystallography: Rb4[''trans''-[Rh(H<sub>2</sub>O)<sub>2</sub>(NO<sub>3</sub>)<sub>4</sub>][Rh(NO<sub>3</sub>)<sub>6</sub>][1] and Cs2[-[Rh(NO<sub>3</sub>)<sub>5</sub>].[2] Rhodium nitrates are of interest because nuclear wastes, which contain rhodium, are recycled by dissolution in nitric acid.[3]
Uses
Rhodium(III) nitrate is used as a precursor to synthesize rhodium.[4]
