First, let's draw the Lewis Structure for XeF_6: The total number of electrons in XeF_6 is 8+(7xx6)=50 electrons. If the electron lone pair were localized on one face, the molecule should distort to a C 3v geometry, but if the electron lone pair were localized on an edge the molecule should distort to a C 2v geometry. Atomization energies at 0 K and heats of formation at 0 and 298 K are predicted for XeF3+, XeF3−, XeF5+, XeF7+, XeF7−, and XeF8 from coupled cluster theory (CCSD(T)) calculations with effective core potential correlation-consistent basis sets for Xe and including correlation of the nearest core electrons. What happens here is that the fluorine atoms are placed in the vertices of the octahedron while the lone pairs move in the space to avoid or reduce the repulsion. Important Points To Remember.
