The ideal bond angle of PF5 is 90o (axial) and 120o (equatorial) Thus, the shape of the molecule has no deviation from the original structure due to the absence of lone pair of electrons. Since the axial bond pairs agonize more repulsive interaction from the equatorial bond pairs, the axial bonds tend to be slightly longer. For many cases, such as trigonal pyramidal and bent, the actual angle for the example differs from the ideal angle, and examples differ by different amounts.
