• Source: Curium(III) iodide

Curium(III) iodide is the chemical compound with the formula CmI3. Since all isotopes of curium are only artificially produced, the compound has no natural occurrence.




Synthesis


Elemental curium and iodine can be reacted to synthesize curium(III) iodide.

2Cm + 3I2 → 2CmI3
Also by the reaction of curium(III) chloride with ammonium iodide:

CmCl3 + 3NH4I → CmI3 + 3NH4Cl
