'''Iridium hexafluoride''', also '''iridium(VI) fluoride''', (IrF<sub>6</sub>) is a compound of ] and ] and one of the seventeen known binary ]s. It is one of only a few compounds with iridium in the ] +6. |
|
|
|
|
|
== Synthesis == |
|
|
Iridium hexafluoride is made by a direct reaction of iridium metal in an excess of elemental ] gas at 300 °C. However, it is thermally unstable and must be frozen out of the gaseous reaction mixture to avoid dissociation. |

== Description == |
|
|
Iridium hexafluoride is a yellow crystalline solid that melts at 44 °C and boils at 53.6 °C.<ref name="CRC_HANDBOOK_IrF6"/> The solid structure measured at −140 °C is ] space group ''Pnma''. ] are ''a'' = 9.411 ], ''b'' = 8.547 Å, and ''c'' = 4.952 Å. There are four ]s (in this case, discrete molecules) per ], giving a density of 5.11 g·cm<sup>−3</sup>.<ref name="D_BLOCK_XF6"/> |
|
|
|
|
|
The IrF<sub>6</sub> molecule itself (the form important for the liquid or gas phase) has ], which has point group ('']''). The Ir–F ] is 1.833 Å.<ref name="D_BLOCK_XF6"/> |
|
|
|
|

Calculations suggest that ] might react with iridium hexafluoride at 39 GPa to form IrF<sub>8</sub>.<ref>{{cite journal | last1=Lin | first1=Jianyan | last2=Zhao | first2=Ziyuan | last3=Liu | first3=Chunyu | last4=Zhang | first4=Jing | last5=Du | first5=Xin | last6=Yang | first6=Guochun | last7=Ma | first7=Yanming | title=IrF8 Molecular Crystal under High Pressure | journal=Journal of the American Chemical Society | publisher=American Chemical Society (ACS) | volume=141 | issue=13 | date=2019-03-13 | issn=0002-7863 | doi=10.1021/jacs.9b00069 | pages=5409–5414| pmid=30864432 | s2cid=76664353 }}</ref> |
