Cerium(III) iodide (CeI3) is the compound formed by cerium(III) cations and iodide anions.
Cerium metal reacts with iodine when heated to form cerium(III) iodide: [2]
It is also formed when cerium reacts with mercury(II) iodide at high temperatures: [2]
Cerium(III) iodide adopts the plutonium(III) bromide crystal structure. [3] [4] It contains 8-coordinate bicapped trigonal prismatic Ce3+ ions. [1]
Cerium(III) iodide is used as a pharmaceutical intermediate [5] and as a starting material for organocerium compounds. [2]
