Americium hexafluoride is an inorganic chemical compound of americium metal and fluorine with the chemical formula AmF6. It is still a hypothetical compound.[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 AmF6 can be prepared by in both the condensed and gaseous states by the reaction of KrF2 with AmF3 in anhydrous HF at 313–333 K.[5]
- AmF
3 + KrF
2 → AmF
6 + Kr[6]
- AmF
