    Based on this determination, the VSEPR geometry of this molecule is trigonal bipyramidal. As you can see under the label “symmetry”, this molecule has a D 3h symmetry. This means that the molecule belongs to a geometric family of “dihedral” molecules with three rotational modes through a horizontal plane (i.e., 3h).
