The Jahn-Teller Theorem
"for a non-linear molecule in an electronically degenerate state, distortion must occur to lower the symmetry, remove the degeneracy, and lower the energy"
(Jahn and Teller, Proc. Roy. Soc., 1937, A161, 220)
The JT Effect in the structures of Cu(II) complexes.
An example of a static JT Effect
An example of a dynamic JT effect. The lattice structure of this complex changes to one of much lower symmetry when the complex is cooled to a sufficiently low temperature.
