properties

Aluminum iodide

Aluminum iodide is a white powder made up of colorless flakes. It is sensitive to moisture and decomposes when heated in air to form iodine and aluminum oxide . It crystallizes in a monoclinic structure with the space group P 2 ₁ / c (space group no.14 ) , a = 9.591 Å, b = 6.069 Å, c = 11.902 Å, β = 108.05 °, in which it is called the dimer Al ₂ I ₆ is present. Template: room group / 14

use

Aluminum iodide is used in organic synthesis as a catalyst to break certain types of C – O and N – O bonds. It splits aryl ethers and decomposes epoxides . It can also be used to make iodinated organic compounds.
