Rhodium(III) chloride

Rhodium(III) chloride usually refers to hydrated rhodium trichloride, a molecular compound with the formula RhCl3(H2O)3 (CAS number3, a polymeric solid with the AlCl3 structure. Inexperienced workers sometimes confuse the two rhodium chlorides, but their behavior is completely different. Most chemistry ascribed to "rhodium trichloride" requires the use of the hydrated form. Some procedures calling for a rhodium chloride imply the use of Na3RhCl6, which is also a molecular, hence reactive, form of Rh(III).

Rhodium(III) chlorides are the products of the separation of rhodium from the other platinum group metals.
