Argon fluorohydride (HArF) is the first known compound of the chemical element argon.

Discovery

The discovery of this first argon compound is credited to a group of Finnish scientists, led by Markku Räsänen. On 24 August 2000, in the journal Nature, they announced their discovery of argon fluorohydride.

Synthesis

This chemical was synthesized by mixing argon and hydrogen fluoride on a caesium iodide surface at −265 °C, and exposing the mixture to ultraviolet radiation. This caused the gases to combine.

The infrared spectrum of the resulting gas mixture shows that it definitely contains chemical bonds, albeit very weak ones; thus, it is argon hydrofluoride. Its chemical bonds are stable only if the substance is kept at temperatures below −256 °C; upon warming, it decomposes into argon and hydrogen fluoride.
