The axial bonds are longer than the equatorial bonds.

In case of PCl5 the bond pairs present on the axial position suffer more repulsion than that of bond pairs present on the equatorial position.

Actually each bond pair present at the axial position has to face the repulsion of three equatorial bond pairs, due to this the bond is stretched and hence the bond length increases.

but in case of equatorial bonds, the repulsion are lesser as compared to the axial bonds so they are shorter.
