[edit] Discovery

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

[edit] Synthesis

This chemical was sythesized by mixing argon and hydrogen fluoride on to caesium iodide at −265 °C and exposing the mixture to ultraviolet radiation. This causes the gases to react to form argon fluorohydride.

Examining the infrared spectrum of the substance, they found that chemical bonds had formed, albeit very weak ones, so long as the substance was kept at temperatures below −256°C. Upon warming it decomposes into argon and hydrogen fluoride.
