Trigonal bipyramidal usually has 2 different bond angles (90 and 120) when all the attachments are identical. For trigonal pyramidal geometry the bond angle is slightly less than 109.5 degrees, around 107 degrees. Three of the bonds are arranged along the atom’s equator, with 120° angles between them; the other two are placed at the atom’s axis. Furthermore, the angle between bonded pairs of electrons in a trigonal planar is around 120 degrees whereas the bond angle in trigonal pyramidal is around 107 degrees. A molecule with two electron domains will display bond angles of how many degrees? Which spatial orientation will involve more than one bond angle value? This is much better than with your geometry.

In PCl 5 the 5sp 3 d orbitals of phosphorus overlap with p orbitals of chlorine atoms. Pages 20. In PCl 5, P atom has five electron pairs at its valence shell so it takes trigonal bipyramidal geometry with bond angle 120 ˚ and 90 ˚ so that there exists minimum repulsion between valence electron pairs at P atom to attain minimum energy and maximum stability according to VSEPR theory. Here, SF4 bond angles are around 102 degrees in the equatorial plane and around 173 degrees between the axial and equatorial positions. However, the geometry about the metal is distorted because of the acute ligand N–Ni–N bite angles (∼80° av) and hence the axial and equatorial angles deviate from the ideal, 180 and 120°, by 9°.
