Relativistic coupled-cluster calculations on XeF6: Delicate interplay between electron-correlation and basis-set effects.
Often, the structure is described as having a stereochemically active but fluxional lone pair, which is generally accurate; however, VSEPR cannot be used to predict the region of space which the lone pair occupies. Thanks for contributing an answer to Chemistry Stack Exchange! Is it possible to rotate a window 90 degrees if it has the same length and width?

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. If you are considering the viability of a distortion to $T_\mathrm d$, then you should be looking for an $\mathrm{A_1}$ component in the second row, not $\mathrm{A_{1g}}$. Jmol.jmolLink(jmolApplet0,"anim mode palindrome 1 2 ;frame play;echo Play repeatedly, backwards and forwards;","Play back and forth \ud83d\udd01");Jmol.jmolBr() Its one of xenons three binary fluorides.
