Krypton(IV) fluoride is a hypothetical inorganic chemical compound of krypton and fluorine with the chemical formula KrF4. At one time researchers though they made it, but the claim was discredited.[1] The compound is predicted to be difficult to make and unstable if made.[2] 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:[3]
- Kr + 2F2 → KrF4
Physiscal properties
The claimed compound formed white crystalline solid.[4] Thermally, it is less stable than XeF4.[5]
