Americium hexafluoride

Chemical compound From Wikipedia, the free encyclopedia

Americium hexafluoride is a hypothetical inorganic chemical compound of americium and fluorine with the chemical formula AmF
6
.[1][2] Synthesis by fluorination of americium tetrafluoride was unsuccessfully attempted in 1990.[3] A thermochromatographic identification in 1986 remains inconclusive.[4] Calculations suggest that it may be distorted from octahedral symmetry.[4]

Synthesis

It is proposed that AmF
6
can be prepared by in both the condensed and gaseous states by the reaction of KrF
2
with AmF
3
in anhydrous HF at 313–333 K.[5]

2 AmF3 + 3 KrF2 → 2 AmF6 + 3 Kr[6]
