Sir in trigonal bi pyramidal geometry, axial bonds are longer than equitorial bonds... But what about pentagonal bipyramidal geometry (eg IF7)

Dear student 
In a TBP molecule, the equatorial bonds are spaced apart from each other by 120 degrees, resulting in lesser repulsion; compared to the axial bonds at 90 degrees. The reduced repulsion leads to greater stability of the equatorial bonds.
In contrast, the equatorial bonds in a PBP molecule are separated by 72 degrees which results in them being less stable when compared to the axial bonds.
