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][verification needed][4]} Calculations suggest it would have octahedral molecular geometry.^[1]

So far, out of all possible krypton fluorides, only krypton difluoride (KrF₂) has actually been synthesized.^{[citation needed]}
