Osmium(IV) fluoride is an inorganic chemical compound of krypton and fluorine with the chemical formula KrF4.[1]

Synthesis

Passing electric discharge through krypton-fluorine mixture:[2]

Kr + 2F2 → KrF4

Physiscal properties

The compound forms white crystalline solid.[3] Thermally, it is less stable than XeF4.[4]

Chemical properties

Chemically active.

On hydrolysis the compound yields krypton, oxygen, and hydrogen fluoride.

At 60 °C krypton tetrafluoride decomposes:[4]

KrF4 → Kr + 2F2
