Americium hexafluoride

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]
