In fact, the structure of XeF 6 is based upon a distorted octahedron, probably towards a monocapped octahedron. The preference of XeF6 for either a trigonally distorted or a regular octahedral structure is determined by a delicate balance of several competing factors. The distribution proves the molecule cannot be a regular octahedron vibrating in independent normal modes. The effect of this fluxional process is to average all the fluorine positions.

It has a distorted octahedral structure as per the VSEPR theory,it is having 6 bond pairs and one lone pair together constituting 7 electron pair Xe F 6 (ein. It is difficult to settle the geometry of the lowest energy configurtion because the geometry of XeF 6 changes rapidly with time, that is, it is fluxional. Gillespie deliberately neglects hybridization in the first approximation and considers that lone pairs have a strong tendency to be directed, not inert. The extra pair of electrons is said to do what might be thought of as a fractional float around the molecule trying to balance the overall electron distribution. So the distorted octahedral structure is the … So the distorted octahedral structure is the best geometrical choice. 17.
