'''Argon fluorohydride''' (systematically named '''fluoridohydridoargon''') or '''argon hydrofluoride''' is an ] with the ] HArF (also written ArHF). It is a compound of the ] ].

==Discovery== == Synthesis ==
This chemical was synthesized by mixing ] and ] on a ] surface at 8 K (−265 °C), and exposing the mixture to ultraviolet radiation. This caused the gases to combine.
The discovery of this first ] compound is credited to a group of Finnish scientists, led by Markku Räsänen. On 24 August 2000, in the journal '']'', they announced their discovery of argon fluorohydride.<ref>{{cite journal | last = Khriachtchev | first = Leonid | coauthors = Mika Pettersson, Nino Runeberg, Jan Lundell & Markku Räsänen | date = 24 August 2000 | title = A stable argon compound | journal = Nature | volume = 406 | pages = 874–876 | doi = 10.1038/35022551 | url = http://www.nature.com/nature/journal/v406/n6798/abs/406874a0.html | pmid = 10972285 | issue = 6798 }}</ref>


The ] of the resulting gas mixture shows that it definitely contains chemical bonds, albeit very weak ones; thus, it is argon fluorohydride, and not a ] or a mixture of argon and hydrogen fluoride. Its chemical bonds are stable only if the substance is kept at temperatures below 27 K (−246 °C); upon warming, it decomposes into argon and hydrogen fluoride.<ref name=ASAC/>
==Synthesis==
This chemical was synthesized by mixing argon and ] on a ] surface at −265&nbsp;°C, and exposing the mixture to ultraviolet radiation. This caused the gases to combine.
