Dodecahedral molecular geometry

Examples| Mo(CN)4−8
Point group| D2d
Coordination number| 8
μ (Polarity)| 0

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 (also known as a trigonal dodecahedron). This shape has D2d symmetry and is one of the three common shapes for octacoordinate transition metal complexes, along with the square antiprism and the bicapped trigonal prism.[1][2]

One example of the dodecahedral molecular geometry is the Mo(CN)4−8 ion.[2]
