Krypton tetrafluoride
Chemical compound
From Wikipedia, the free encyclopedia
Krypton(IV) fluoride is a hypothetical inorganic chemical compound of krypton and fluorine with the chemical formula KrF4. At one time researchers thought they had synthesized it, but the claim was discredited.[1] The compound is predicted to be difficult to make and unstable if made.[2] However, it is predicted to become stable at pressures greater than 15 GPa.[3] Theoretical analysis indicates KrF4 would have an approximately square planar molecular geometry.[2]

Synthesis
The claimed synthesis was by passing electric discharge through krypton-fluorine mixture:[4]
- Kr + 2F2 → KrF4
