I am trying to figure out if a distortion from $O_h$ can take place and to which (lower symmetry) point group it would be. Xe +2 F2 -> XeF4. From what you have written, I sense that you're trying to "look for an $\mathrm{A_{1g}}$ component", which isn't what you should be looking for, because something that transformed as $\mathrm{A_{1g}}$ in $O_\mathrm h$ symmetry may not necessarily transform as "$\mathrm{A_{1g}}$" in the lower symmetry. You should be asking whether the $\color{blue}{\text{blue}}$ bit contains the $\color{red}{\text{red}}$ bit. It puts DOI: 10.1063/1.1669471.

Its one of xenons three binary fluorides. The fluorine atoms are positioned in the octahedrons vertices, while the lone pairs wander around in the space to prevent or lessen the repulsion. The structure of XeF6 is same as KrF6 and has no lone pairs. A mountain swallowtail butterfly has only a mirror that cuts through the head, thorax, and abdomen. Along with this, its Hybridization can also be described as an sp, Molecular Geometry and Bond Angles: Importance, Due to the presence of a lone pair, it is used in the manufacturing of bulbs, These lonely pairs get excited when we impart the electric charge between them, Due to these lone pairs, xenon hexafluoride is filled in electric bulbs and flashbulbs, Thats why xenon hexafluoride gets excited in the flow of nominal current, . J. Chem. different C(3v) minima on the pseudorotation potential energy surface, and the O(h) structure is a higher-order saddle point leading to the C(2v) transition states. However, relativistic effects as well as electron correlation both favour the $O_\mathrm{h}$ structure. It consists of 6 bond pairs and one lone pair. Albright, T. A.; Burdett, J. K.; Whangbo, M.-H. Orbital Interactions in Chemistry, 2nd ed. vegan) just to try it, does this inconvenience the caterers and staff? What is the structure of the hypothetical xenon octafluoride? J. Chem.

E.; Sharpe, A. G. Inorganic Chemistry, 4th ed. 8600 Rockville Pike Federal government websites often end in .gov or .mil. It is similar to the one for $\ce{SF6}$ (see here), except that there are two more electrons: This opens up the possibility of a second-order JahnTeller distortion, and I have described the mathematical basis of this elsewhere. Of course, $\mathrm{T_2}$ does not contain $\mathrm{A_1}$, so the distortion to $T_\mathrm{d}$ isn't favourable. b. ability to interbreed and produce viable, fertile offspring. These lonely pairs get excited when we impart the electric charge between them. There is still a lack of agreement on the exact details of the potential energy surface.
