The Indigo® Molecular Geometry Shapes VSEPR Set, only $19.95, includes three models that illustrate trigonal bipyramidal geometry. One has five bonded pairs. The second has 4 bonded pairs and a lone pair. The third has three each bonded and and 2 lone pairs. The red terminal atoms in the indicate they are coplanar with the central atom. All atoms and bonds are autoclavable.
