Again, to drive home the point, you shouldn't be looking for whether the $\color{blue}{\text{blue}}$ bit contains $\mathbf{A_{1g}}$. Likewise, $\mathrm{T_{1u}}$ in $O_\mathrm h$ goes to $\mathrm{A_{2u} + E_u}$ in $D_\mathrm{3d}$, which in turn goes to $\mathrm{A_1 + E}$ in $C_\mathrm{3v}$. Apart from this, other molecular forms of xenon hexafluoride are XeF, . First you go from $O_\mathrm h$ to $D_\mathrm{3d}$, and then you go from $D_\mathrm{3d}$ to $C_\mathrm{3v}$. Weller, M.; Overton, T.; Rourke, J.; Armstrong, F. Inorganic Chemistry, 6th ed; Oxford University Press: Oxford, U.K., 2014. XeF6 Molecular Geometry contains one atom of xenon and six atoms of fluorine. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. Very sophisticated coupled-cluster calculations (CCSD(T)-F12b) were carried out by Peterson et al., and led to the conclusion that the $C_\mathrm{3v}$ structure was the ground state.13 The eight equivalent $C_\mathrm{3v}$ structures (an octahedron has eight faces) underwent interconversion via $C_\mathrm{2v}$ transition states $\pu{1.08kcal/mol}$ higher in energy. Occurrence. Point groups are mathematical constructs that capture all the non-translation symmetry options that can be performed on an object (reflection, rotation, or rotoinversion). Similarly, fluorine belongs to group 17 of the periodic table and has 7 valence electrons. The bond angle of xenon hexafluoride is 90 and 72. The minimum energy conformer is probably $C_\mathrm{3v}$. 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.

Wang H, Wang S, Yan G, Yamaguchi Y, Schaefer HF 3rd. Lets understand the meaning of XeF6 molecular geometry and bond angles meaning. Instead, a molecule's point group can be determined by following a set of steps which analyze the presence (or absence) of particular symmetry elements. Sorry, this must have slipped my mind when you posted it (I think I was working on my thesis). The bond angle of xenon hexafluoride is 90 and 72. the molecule in the C3V point group instead of the Oh point The C(2v) conformer is a transition state connecting the 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. Computational studies of $\ce{XeF6}$ have generally been plagued by a strong dependency on the level of theory and on the basis sets used, due to the very small energy differences between the relevant conformers. The Hybridization of xenon hexafluoride can be calculated by checking the numbers of lone pairs and bond pairs in the geometry. E 2S 4 C 2 (z) 2C' 2 2 d; Examples.
