Trigonal Bipyramidal

The Trigonal Bipyramidal Geometry: A Molecule's Perfect Shape Molecules exhibiting trigonal bipyramidal geometry are characterized by a unique arrangement of atoms, with five atoms located at the vertices of an equilateral triangle and a fifth atom sitting atop this triangular base. This specific configuration is achieved through a combination of electron pair repulsion and molecular orbital overlap. In a molecule displaying trigonal bipyramidal geometry, three bond pairs occupy the equatorial positions, while two lone pairs reside in the axial positions. As a result, these molecules exhibit a symmetrical shape with five atoms arranged around a central axis.
