Chemical compound
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.[ 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(H2 O)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]
Uses
Rhodium(III) nitrate is used as a precursor to synthesize rhodium.[ 7]
