Krypton hexafluoride is an inorganic chemical compound of krypton and fluorine with the chemical formula KrF
6. It is still a hypothetical compound.[1]
History
In 1933, Linus Pauling predicted[2] that the heavier noble gases would be able to form compounds with fluorine and oxygen. He also predicted the existence of krypton hexafluoride.[3] So far, out of all possible krypton fluorides, only krypton difluoride (KrF
2) has been actually formed. It is a white crystalline solid that decomposes spontaneously at normal temperatures.[4] This fact leads to suggest that krypton hexafluoride is also an unstable compound.
