Use MathJax to format equations. This was occasionally presented as evidence for an undistorted structure, but the calculations did not take into account the possibility of a highly fluxional process, and later Bernstein and Pitzer showed that depending on the barrier height, dipole moments up to $\pu{0.6D}$ could be plausible.7 On top of that, the distorted conformers were not expected to have large dipole moments, as the dipole moment of the lone pair would oppose the net dipole moments of the $\ce{Xe-F}$ bonds. DOI: 10.1063/1.1667921. As far as simple bonding theories go, the best explanation is given by qualitative molecular orbital theory.

Vote count: 32 Below the molecular orbital diagram for $\ce {XeF6}$ (from What is the molecular structure of xenon hexafluoride?) This tells you that if you decrease the symmetry of the system from $O_\mathrm h$ to $T_\mathrm d$, then anything that previously transformed as $\mathrm{A_{1g}}$ will now transform as $\mathrm{A_1}$. XeF6 is a white crystalline solid at room temperature and melts at about 325 K. A mixture of 0.0600 g of Xe and 0.0304 g of F2 is sealed into a 100.0-mL bulb.

The molecular geometry of XeF6 is the sp3d3, which is also called a distorted octahedral or square bipyramidal after Hybridization. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. proofreading services. Xenon tetrafluoride (XeF 4) is a square planar molecule, and XeF 6 in the gas phase is a distorted octahedral molecule arising from the presence of an "extra" pair of nonbonding electrons in the xenon valence shell. In the case of $\ce{XeF6}$, these lead to very small differences between the two structures.12. By distortion to a lower symmetry, the HOMO and LUMO are allowed to mix, which leads to a stabilising interaction. Average rating 4.6 / 5. projects. So, the product B is XeO2F2.
