... The coordination chemistry of pyridyl oximes is reviewed. Simple pyridyl oximes have the general formula (py)C(R)NOH, where py is a pyridyl group (2-, 3- or 4-) attached to the oxime carbon atom and R can be a donor or a non-donor group. There are also ligands containing more pyridyl and/or oxime gr ...

Jahn–Teller effect



The Jahn–Teller effect, sometimes also known as Jahn–Teller distortion, describes the geometrical distortion of molecules and ions that is associated with certain electron configurations. This electronic effect is named after Hermann Arthur Jahn and Edward Teller, who proved, using group theory, that orbital nonlinear spatially degenerate molecules cannot be stable. The Jahn–Teller theorem essentially states that any nonlinear molecule with a spatially degenerate electronic ground state will undergo a geometrical distortion that removes that degeneracy, because the distortion lowers the overall energy of the species. For a description of another type of geometrical distortion that occurs in crystals with substitutional impurities see article off-center ions.
