See Answer Determine the symmetry elements and the point group of the molecules. One of these is xenon hexafluoride (XeF6), which can be prepared by heating a mixture of xenon and fluoride gases. The oxidation state of xenon in Xenon Difluoride is +2. then it is clear that because the $\color{blue}{\text{blue}}$ $\mathrm{A_1 + E}$ shares one irrep in common with the $\color{red}{\text{red}}$ $\mathrm{A_1}$ component, the HOMOLUMO mixing is allowed in $C_\mathrm{3v}$ symmetry, and this provides a qualitative argument for why distortion to $C_\mathrm{3v}$ symmetry is favoured. 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. Be the first to rate this page. Along with this, its Hybridization can also be described as an sp3d3 arrangement. The bond angle of xenon hexafluoride is 90 and 72.
