In octahedral complexes, the Jahn–Teller effect is most pronounced when an odd number of electrons occupy the e g orbitals. This situation arises in complexes with the configurations d, low-spin d or high-spin d complexes, all of which have doubly degenerate ground states. In such compounds the e g orbitals involved in the degeneracy point directly at the ligands, so distortion can result in a large energetic stabilisation. Strictly speaking, the effect also occurs when there is a degeneracy due to the electrons in the t 2g orbitals (i.e. configurations such as d or d, both of which are triply degenerate). In such cases, however, the effect is much less noticeable, because there is a much smaller lowering of repulsion on taking ligands further away from the t 2g orbitals, which do not point directly at the ligands (see the table below). The same is true in tetrahedral complexes (e.g. manganate : distortion is very subtle because there is less stabilisation to be gained because the ligands are not pointing directly at the orbitals.
