Americium hexafluoride is an inorganic chemical compound of americium metal and fluorine with the chemical formula AmF
6. 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
[edit]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]
