Argon florohidrür (HArF), kimyasal element argonun bilinen tek nötr bileşiğidir.

Keşfedilmesi

Bu ilk argon bileşiği, Markku Räsänen liderliğindeki bir grup Fin bilim insanı tarafından keşfedildi. Buluşlarını 24 Ağustos 2000 tarihinde Nature dergisinde açıkladılar.[1]

Sentezi

Bu kimyasal madde, argon ve hidrojen florürü -265 °C (8 K) derecede bir sezyum iyodür yüzeyde karıştırarak ve ultraviyole radyasyona maruz bırakarak sentezlendi. Bu işlem, gazları birleşmesine neden oldu.

Ortaya çıkan gaz karışımının kızılötesi spektrumu, çok zayıf da olsa kimyasal bağlar olduğunu kesin olarak gösterdi. Bu nedenle, bir süpermolekül veya argon ve hidrojen florür karışımı olmadığı kanıtlandı. Kimyasal bağları yalnızca maddenin -256 °C (17 K) derece altında tutulduğunda stabildir; ısınmayla argon ve hidrojen florüre ayrışır.
