    Hydrated rhodium trichloride is reduced by carbon monoxide, ethylene, and trifluorophosphine to give rhodium(I) complexes Rh 2 Cl 2 L 4 (L = CO, C 2 H 4, PF 3). When treated with triphenylphosphine , hydrated rhodium trichloride converts to the maroon-colored RhCl(P(C 6 H 5 ) 3 ) 3 , which is known as Wilkinson's catalyst .

    At 3% fission products by weight, one ton of used fuel will contain about 400 grams of rhodium. The longest lived radioisotope of rhodium is 102m Rh with a half-life of 2.9 years, while the ground state (102 Rh) has a half-life of 207 days. [1] Each kilogram of fission rhodium will contain 6.62 ng of 102 Rh and 3.68 ng of 102m Rh.
