Rhodium(III) iodide is an inorganic compound with the formula RhI3. It is a black solid.[1]
Rhodium(III) iodide can be synthesised by the reaction of aqueous potassium iodide with rhodium(III) bromide.[1]
RhI3 adopts same crystal structure motif as AlCl3 and YCl3. The structure consists of cubic close-packed iodide ions and rhodium ions filling a third of the octahedral interstices, forming a layers.[2]
Rhodium(III) iodide is only known in the anhydrous form. Unlike the other rhodium(III) halides, it does not form hydrates.[1] The related anion [RhI6]3− was previously thought not to form[1] but has since been prepared by diffusion of RhCl3·3H2O through a layer of hydroiodic acid into piperazine.[3]
