'''Zirconium(IV) iodide''' is the [[chemical compound]] with the formula [[Zirconium|Zr]][[Iodine|I<sub>4</sub>]]. It is the most readily available iodide of zirconium. It is an orange-coloured solid that degrades in the presence of water. The compound was once prominent as an intermediate in the purification of zirconium metal. |
|||
==Structure== |
|||
Like most binary metal halides, zirconium(IV) iodide adopts a polymeric structure. As characterized by [[X-ray crystallography]], the compound consists of octahedral Zr(IV) centers interconnected by four doubly bridging iodide ligands. The Zr-I distances of 2.692 (terminal) and 3.030 Å<ref>{{cite journal|first1=B.|last1=Krebs|first2=G.|last2=Henkel|first3=M.|last3=Dartmann|title=Kristallstruktur von Zirkoniumtetrajodid ZrI<sub>4</sub>: ein neuer AB<sub>4</sub>-Strukturtyp|journal=Acta Crystallogr.|year=1979|volume=B35|issue=2|page=274-278|doi=10.1107/S0567740879003344}}</ref><ref>{{cite journal|first1=S.

|||
==Synthesis and reactions== |
|||
This compound is volatile, subliming as intact tetrahedral ZrI<sub>4</sub> molecules. It is prepared by the direct reaction of powdered zirconium metal and iodine.<ref name=IS>{{cite book|author=Eberly, K. C.|title=Inorganic Syntheses|chapter=Zirconium(IV) Iodide|year=1963|volume=7|pages=52–54|doi=10.1002/9780470132388.ch13|isbn=978-0-470-13238-8}}.</ref> |

[[Pyrolysis]] of zirconium(IV) iodide gas by contact of hot wire was the first industrial process for the commercial production of pure ductile metallic zirconium. This [[crystal bar process]] was developed by [[Anton Eduard van Arkel]] and [[Jan Hendrik de Boer]] in 1925.<ref>{{cite journal | doi = 10.1002/zaac.19251480133 | title = Darstellung von reinem Titanium-, Zirkonium-, Hafnium- und Thoriummetall | first1 = A.
