Examples of this molecular geometry are phosphorus pentafluoride (PF5), and phosphorus pentachloride (PCl5) in the gas phase. The molecule is three dimensional as opposed to the boron hydride case which was a flat trigonal planar molecular geometry because it did not have a lone electron pair. The reason is that the lone pair prefers one of the equatorial positions. For example, if there is 4 X atoms and 1 Y atom attached to the central atom, Y could either be in an equatorial position or in an axial position. Do not assume the Lewis structure is drawn to indicate the geometry of the molecule.
