Dodecahedral molecular geometry

In chemistry, the dodecahedral molecular geometry describes the shape of compounds where eight atoms or groups of atoms or ligands are arranged around a central atom defining the vertices of a snub disphenoid. This shape has D_2d symmetry and is one of the three common shapes for octacoordinate transition metal complexes, along with the square antiprismatic [molecular geometry|square antiprism] and the bicapped trigonal prism.
One example of the dodecahedral molecular geometry is the ion.
