Americium hexafluoride

Americium hexafluoride is an inorganic chemical compound of americium metal and fluorine with the chemical formula. It is still a hypothetical compound. Synthesis by fluorination of americium tetrafluoride was unsuccessfully attempted in 1990. A thermochromatographic identification in 1986 remains inconclusive. Calculations suggest that it may be distorted from octahedral symmetry.

Synthesis
It is proposed that can be prepared by in both the condensed and gaseous states by the reaction of Krypton(II) fluoride with Americium(III) fluoride in anhydrous HF at 313–333 K.
