Three electron pairs are inclined at 120°.
Two electron-pairs are at 90° with the first three.

Structure is trigonal bipyramidal.

The structure and bond angle as predicted by Sidgwick-Powell theory for a molecule with five electron pairs in the outer shell would be trigonal bipyramidal.

In a trigonal bipyramidal structure, there are three equatorial electron pairs arranged in a flat triangle, and two axial electron pairs located above and below the triangle. The bond angles in the equatorial plane are approximately 120 degrees, while the bond angles between the axial and equatorial positions are approximately 90 degrees.

So, in this case, the structure would be trigonal bipyramidal with bond angles of approximately 120 degrees in the equatorial plane and approximately 90 degrees between the axial and equatorial positions.
