Cerium(III) iodide (CeI3) is the compound formed by cerium(III) cations and iodide anions.




Preparation


Cerium metal reacts with iodine when heated to form cerium(III) iodide:

2 Ce + 3 I2 → 2 CeI3
It is also formed when cerium reacts with mercury(II) iodide at high temperatures:

2 Ce + 3 HgI2 → 2 CeI3 + 3 Hg




Structure


Cerium(III) iodide adopts the plutonium(III) bromide crystal structure. It contains 8-coordinate bicapped trigonal prismatic Ce3+ ions.




Uses


Cerium(III) iodide is used as a pharmaceutical intermediate and as a starting material for organocerium compounds.
