Infobox references

Radon hexafluoride is a binary chemical compound of radon and fluorine with the chemical formula RnF6.[1][2][3] This is still a hypothetical compound that has not been synthesized so far.

## Potential properties

The compound is calculated to be less stable than radon difluoride. Radon hexafluoride is expected to have an octahedral molecular geometry, unlike the C3v of xenon hexafluoride.[4][5]

The Rn-F bonds in radon hexafluoride is predicted to be shorter and more stable compared to Xe-F bonds in xenon hexafluoride.[5]
