Indium (III) iodide is an inorganic chemical compound of indium from the group of iodides .

Extraction and presentation

Indium (III) iodide can be obtained by reacting indium with iodine vapor .

{\ displaystyle \ mathrm {2 \ In + 3 \ I_ {2} \ longrightarrow 2 \ InI_ {3}}}

Aqueous solutions of indium (III) iodide can easily be obtained from indium and hydroiodic acid . Anhydrous indium (III) iodide separates from these when concentrated.

properties

Indium (III) iodide is a pale yellow, very hygroscopic monoclinic solid ( space group P 2 ₁ / c (space group no. 14) , a = 9.837 Å , b = 6.102 Å, c = 12.195 Å, β = 107.69 °), which melts to a dark brown liquid at 210 ° C and is readily soluble in water. Its crystals consist of dimeric molecules. The yellow β-form slowly transforms into the red α-form. In the presence of steam, the compound reacts with oxygen at 245 ° C to form indium (III) oxide iodide. Template: room group / 14

use

Indium (III) iodide is used to produce vinyl and methyline data, which undergo regioselective reactions with cinnamyl bromide . It also serves as a catalyst in organic chemistry.
