Americium hexafluoride explained

Americium hexafluoride is an inorganic chemical compound of americium metal and fluorine with the chemical formula . 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 can be prepared by in both the condensed and gaseous states by the reaction of with in anhydrous HF at 313–333 K.^[5]
