It was found that the Jahn–Teller crystal distortion occurs in both models, as the potential energy curves provide the local minimum points, At the experimental amplitude of the Jahn–Teller crystal distortion 0,15 Å, J ab values for Cu 4 F 4 F 12 and Cu 4 F 4 F 16 models were 6,784 and 6,162 cm − 1, respectively, showing the ferromagnetic interaction, They were well consistent with the experimental …

Overview
Jahn-Teller Distortions Introduction, This leads to a break in degeneracy which stabilizes the molecule and by consequence, reduces its symmetry, Elongation, Figure 2: Illustration of tetragonal distortion elongation for an octahedral complex, This is due to the d Compression, Figure 4:

Jahn-Teller Distortions
Jahn-Teller distortion is a geometric distortion of a non-linear molecule to reduce its symmetry and energy, This distortion is typically observed in octahed This distortion is typically
This fact is rationalized on the basis of the different orientation of the Jahn–Teller distortion which modifies the magnetic exchange pathway through the phenoxido bridges from the equatorial – axial connection type observed in 1 to the axial – axial linkages displayed by 2 You have access to this article

The effect of the orientation of the Jahn–Teller
Dynamic Jahn-Teller distortion: In some molecules, the distortion is not seen either due to random movements of bonds which does not allow the measurement within a time frame or else the distortion is so weak as to be negligible, However the distortion can be seen by freezing the molecule at lower temperatures, This condition is referred to as dynamic Jahn-Teller distortion,
Advanced Inorganic Chemistry/Jahn-Teller Distortions
Jahn–Teller distortion is one of the most important reasons of capacity fade for spinel LiMn 2 O 4 as cathode material for lithium ion batteries In this work we proposed an approach to prepare the modified spinel LiMn 2 O 4 to suppress this distortion

The Jahn–Teller distortion describes the geometrical distortion of molecules and ions that result from certain electron configurations [2] This distortion is normally observed among octahedral complexes where the two axial bonds can be compressed or elongated to result in a different bond length from those of the equatorial bonds as shown in figure 1
