A Point Group describes all the symmetry operations that can be performed on a molecule that result in a conformation indistinguishable from the original. This was occasionally presented as evidence for an undistorted structure, but the calculations did not take into account the possibility of a highly fluxional process, and later Bernstein and Pitzer showed that depending on the barrier height, dipole moments up to $\pu{0.6D}$ could be plausible.7 On top of that, the distorted conformers were not expected to have large dipole moments, as the dipole moment of the lone pair would oppose the net dipole moments of the $\ce{Xe-F}$ bonds. . We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The distortion should be mediated by a vibrational mode with symmetry $\mathrm{A_{1g} \otimes T_{1u} = T_{1u}}$, which does indeed lead to a $C_\mathrm{3v}$ structure.

XeF6, reacts with water. When the fluorides of xenon have formed the electrons in the valence shell of xenon get unpaired and are promoted to vacant 5d orbitals. Literature actually suggests $C_{3v}$ as the resulting distortion, but how would I know this when it isn't in the table? Distortions are found to be present when nonrelativistic HartreeFock theory is used, and the addition of polarisation functions (e.g., Xe 4f) to the basis set favours the $C_\mathrm{3v}$ structure.

Group 18 Elements - Toppr-guides I. One of these is xenon hexafluoride (XeF6), which can be prepared by heating a mixture of xenon and fluoride gases. The calculated heats of formation for XeF(6), -62.1 1.4 kcal/mol at 0 K and -64.0 1.4 kcal/mol at 298 K, are the best available values and show that there are serious issues with the experimental values. a. particular roles in a biological community. TL;DR Xenon hexafluoride has a fluxional structure in the gas phase, with multiple rapidly interconverting conformers. XeF 2 was considered to be a possible convenient replacement for elemental fluorine especially in addition reactions to a double bond. This is a result of the strong relativistic effects. provided the first thorough in silico investigation of xenon hexafluoride, along with a number of valence-isoelectronic species.11 They concluded that the balance between an undistorted $O_\mathrm{h}$ structure and a distorted $C_\mathrm{3v}$ structure is governed by competing effects.
