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]
