Otherwise very good overview about the state of the art! The energy decomposition analysis of XeF 6 and SF 6 using neutral and charged fragments EF 5 + F and EF 5+ + F as well as E + F 6 and E 6+ + F 66 indicates that the dominant E-F orbital interactions take place between -orbitals which have t 1u symmetry in the octahedral point group. I know that the compound XeF4 is D4h and my rationale for assigning D4h to XeO2F4 was that it is identical to XeF4 except that instead of 2 lone pairs on the Xe there are 2 double bonded O's. Bernstein, L. S.; Pitzer, K. S. Electric field deflection of molecules with large amplitude motions. Inorganic compounds generally split into cationic and anionic parts to form a lattice and the lattice energy compensates for the energy lost.

Eugene Lemay, Matthew E. Stoltzfus, Patrick Woodward, Theodore E. Brown. While a point group contains all of the symmetry operations that can be performed on a given molecule, it is not necessary to identify all of these operations to determine the molecule's overall point group. It is a powerful fluoridating agent.
Chemistry Final Flashcards | Quizlet \mathrm{A_{1g}} & \mathrm{A_1} \\ Why is xenon hexafluoride not stored in glass? However, because of this lone pair XeF6 does not have a perfect 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. The perfect $O_\mathrm{h}$ structure was found to be a saddle point $\pu{1.80kcal/mol}$ above the ground state, with a threefold degenerate imaginary vibrational frequency.
