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. WebThe marked polyhedral distortion is reflected in large values of the bond-angle variance as well as non-zero values of bond-length distortion (Supporting Information, Table S5).
