Distorted octahedral molecular geometry

In chemistry, the distorted octahedral molecular geometry describes the shape of compounds where six atoms or groups of atoms or ligands are arranged around a central atom (with an electron pair capping the octahedron), defining the vertices of a gyroelongated triangular pyramid. This shape has C_3v symmetry.

Jahn–Teller effect

Main article: Jahn–Teller effect

The term can also refer to octahedral influenced by the Jahn–Teller effect, which is a common phenomenon encountered in coordination chemistry.
