Krypton hexafluoride explained

Krypton hexafluoride is an inorganic chemical compound of krypton and fluorine with the chemical formula . It is still a hypothetical compound.^[1] Calculations indicate it is unstable.^[2]

History

In 1933, Linus Pauling predicted that the heavier noble gases would be able to form compounds with fluorine and oxygen. He also predicted the existence of krypton hexafluoride.^{[3] [4]} Calculations suggest it would have octahedral molecular geometry.^[1]

So far, out of all possible krypton fluorides, only krypton difluoride has actually been synthesized.
