Tricapped trigonal prismatic molecular geometry
In chemistry, the tricapped trigonal prismatic molecular geometry describes the shape of compounds where nine atoms, groups of atoms, or ligands are arranged around a central atom, defining the vertices of a triaugmented triangular prism (a trigonal prism with an extra atom attached to each of its three rectangular faces).[1]

| Examples | ReH2− 9 |
| Point group | D3h |
| Coordination number | 9 |
| μ (Polarity) | 0 |
It is very similar to the capped square antiprismatic molecular geometry, and there is some dispute over the specific geometry exhibited by certain molecules.
