Krypton(IV) fluoride is a hypotheticalinorganic chemical compound ofkrypton andfluorine with the chemical formulaKrF4. 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 indicatesKrF4 would have an approximatelysquare planar molecular geometry.[2]
The claimed synthesis was by passing electric discharge through krypton-fluorine mixture:[4]
The claimed compound formed white crystalline solid.[5] Thermally, it is less stable thanXeF4.[6]
