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]
It is very similar to the capped square antiprismatic molecular geometry, and there is some dispute over the specific geometry exhibited by certain molecules.[citation needed]
Examples
- ReH2−
9[2] - Ln(H
2O)3+
9 (Ln = La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy) - Th(H
2O)4+
9
