The hydrogen atom is not actually electronegative enough to form bonds to xenon. Were the xenon-hydrogen bond to exist, what would be the structure of XeH4

Square planar

Explanation:

There are six electron domains in XeH4. Four of them are bond pairs while two of them are lone pairs.

When a central atom has six electron pairs, the bond pairs occupy the corners of a square while the two lone pairs are found above and below the plane of the square.

This is generally know as the square planar molecular geometry
