Is there a possible distortion of XeF6 from Oh point group to reduced refs 35) will explain how to construct MO diagrams (find the symmetry labels of the atomic orbitals on the central atom; then construct group orbitals/so-called "symmetry-adapted linear combinations" of the terminal atomic orbitals; then overlap them to form MOs). But if you want to obtain it without flipping through every book in the library, this is how you need to do it. The strategy therefore is to carry out the correlation in two steps.

Gas-phase electron diffraction (dating from 1968) showed that the structure was approximately, but not exactly, octahedral: the experimental diffractogram differed from the theoretical diffractogram calculated for a hypothetical octahedral molecule.1 The authors considered a wide range of possible geometrical distortions, and found that $C_\mathrm{2v}$ or $C_\mathrm{3v}$ structures were relatively consistent with the spectrum obtained, with the latter being the most probable configuration.2 These could be interpreted in terms of a stereochemically active lone pair: If we start with an undeformed octahedron we can characterize the deformation to the equilibrium structure in terms of the site of the repulsive lone pair [] Symmetry considerations would seem to dictate that the lone pair be centered on the corner, face, or edge in the equilibrium structure.
