Zirconium (IV) iodide is an inorganic chemical compound of zirconium from the group of iodides .

Extraction and presentation

Zirconium (IV) iodide can be obtained by reacting zirconium with iodine

{\ displaystyle \ mathrm {Zr + 2 \ I_ {2} \ longrightarrow ZrI_ {4}}}

or by reacting zirconium (IV) chloride with aluminum iodide.

{\ displaystyle \ mathrm {3 \ ZrCl_ {4} +4 \ AlI_ {3} \ longrightarrow 3 \ ZrI_ {4} +4 \ AlCl_ {3}}}

properties

Zirconium (IV) iodide is a hygroscopic, pure substance, white, otherwise yellow-orange solid that hydrolyzes in water to form zirconium oxyiodide. It is available in two modifications and, as an α-modification, has a monoclinic crystal structure with the space group P 2 / c (space group no. 13) and as a β-modification has a tetragonal crystal structure with the space group I 4 (no. 79) . It sublimates at 431 ° C. Template: room group / 13Template: room group / 79
