What is the nature of the lone pair of xenon hexafluoride?

How comes the lone pair can be like this (distorted octahedral)?

The lone pair is in an s-orbital. I believe it doesn't distort from octahedral that much.
Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

XeF6 has a non bonding lone pair that occupies a hybrid site resulting in a pentagonal bipyramid (like IF7). Thus, the six ligands should look like a distorted octahedron.

Which orbital does this non-bonding e- pair occupy?

Can this e- pair remove itself spontaneously?
