فلوروهيدريد الأرجون Argon fluorohydride (ويُسمى نظامياً فلوريدوهيدريدوأرجون fluoridohydridoargon) أو هيدروفلوريد الأرجون argon hydrofluoride هو مركب غير عضوي بالصيغة الكيميائية HArF (وتُكتب أيضاً ArHF). وهو مركب للعنصر الكيميائي أرگون.
الاكتشاف
The discovery of this argon compound is credited to a group of Finnish scientists, led by Markku Räsänen.[1] On 24 August 2000, in the journal Nature, they announced their discovery of argon fluorohydride.[2] This discovery caused the recognition that argon could form weakly bound compounds, even though it was not the first compound made with noble gases.[3]
التخليق
This chemical was synthesized by mixing argon and hydrogen fluoride on a caesium iodide surface at 8 K (−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 fluorohydride, and not a supermolecule 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.[2]
