Chemical compound
Krypton hexafluoride is an inorganic chemical compound of krypton and fluorine with the chemical formula KrF6. It is still a hypothetical compound.[1] Calculations indicate it is unstable.[2]
History
[edit ]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 ]
