Samarium(III) iodide is prepared by the reaction of metallic samarium and iodine: [3]
Samarium(III) iodide is a yellow powder that is unstable in air and decomposes in water ( hydrolysis). [1] When heated with metallic samarium, it forms samarium diiodide: [4]
Reduction by hydrogen also affords samarium diiodide:
The compound is commercially available and used in organic reactions as a catalyst. [1]
