WebDec 22, 2024 · In a generalization of the latest achievements in this field, and as a pattern of massive applications, we present here the Jahn–Teller effect (JTE) and pseudo-JTE (PJTE) as general tools in the study of physical and chemical phenomena related to structural properties of polyatomic systems. We show that the JTE and PJTE are no more specific … WebZ-in Jahn-Teller distortion: In this case the energies of orbitals with z factor are increased since the bonds along the z-axis are shortened. This type of distortion is observed in …

WebAug 15, 2024 · The Jahn-Teller effect is a geometric distortion of a non-linear molecular system that reduces its symmetry and energy. This distortion is typically observed among octahedral complexes where the two axial bonds can be shorter or longer than those of the equatorial bonds. This effect can also be observed in tetrahedral compounds.This effect … WebOct 4, 2024 · 2.12: Jahn-Teller Distortion. Lability can often be understood in terms of the d-electron count on the metal. Sometimes, there is a high-lying electron in a formally σ* orbital that destabilizes the complex and weakens a bond to a ligand. A dissociative substitution pathway may be accelerated as a result.
