Although argon is considered chemically inert, at low temperatures it is possible to combine argon with other atoms to form very fragile compounds, which exist only at those very low temperatures. For instance, it can combine with fluorine and hydrogen to form argon fluorohydride (HArF). It is only slightly soluble in water. 

In 1962 the first chemical noble gas compound, formulated as XePtFg, was synthesized by Neil Bartlett. This result spurred intense research activity and led to the discovery of numerous xenon and krypton compounds. In 2000 the formation of the first argon compound, argon fluorohydride (HArF), was reported by Leonid Khriachtchev and colleagues, see also Argon Cavendish, Henry Helium Krypton Neon Ramsay, William Ruthereord, Ernest Soddy, Frederick Strutt, John Xenon. 

Leonid Khriachtchev, Markku Rasanen (1949- ), and their colleagues at the University of Helsinki synthesized argon fluorohydride (HArF) in 2000. They formed a solid matrix of HF in argon at 7.5 K (-447°F or -266°C). Photolysis of the matrix in the vacuum ultraviolet (127-160 nm) dissociates HF into H and F atoms. These form a new species demonstrated by IR spectroscopy and computation to be HArF The calculations indicated resonance of the type ... 

In 2000, researchers at the University of Helsinki, Finland reported production of the compound argon fluorohydride (HArF). This compound was found to be stable up to 40 K.
