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

Extraction and presentation

Zirconium (III) iodide can be obtained by reacting zirconium (IV) iodide with zirconium at 500-700 ° C.

{\ displaystyle \ mathrm {3 \ ZrI_ {4} + Zr \ longrightarrow 4 \ ZrI_ {3}}}

It is also possible to use aluminum instead of zirconium.

{\ displaystyle \ mathrm {3 \ ZrI_ {4} + Al \ longrightarrow 3 \ ZrI_ {3} + AlI_ {3}}}

Gaseous zirconium (III) iodide can be obtained by reacting zirconium with hydrogen iodide at 1100–1500 K.

properties

Zirconium (III) iodide is a blue solid. From a temperature of 275 ° C a disproportionation to zirconium (II) iodide and zirconium (IV) iodide takes place. The compound has an orthorhombic crystal structure with the space group Pmmn (space group no. 59) and a unit cell with the lattice constants a = 1295.4 pm, b = 667.9 pm and c = 729.2 pm. The ions form a one-dimensional chain structure, with two [ZrI _6/2 ] octahedra sharing two opposite triangular faces. Template: room group / 59
