In the last 65 years the properties of Tutton salts containing Cu2+ cations have been interpreted on the basis of elongated complexes induced by a static Jahn–Teller effect (JTE). Through the analysis of experimental data and the results of first-principles calculations, we show here that such an idea, though widely followed, is not correct. By contrast, this work proves that the local geometry of Cu(H2O)62+ units in Tutton salts actually arises from a compressed octahedron although hidden by…

Understanding the Structure and Ground State of the Prototype CuF2 Compound Not Due to the Jahn-Teller Effect.
It is found that CuF64- units are compressed always along the Z local axis with a hole essentially in a 3 z2- r2 antibonding orbital, in agreement with experimental EPR data that already underline the absence of a JTE.
Ground State and Optical Excitations in Compounds with Tetragonal CuF64- Units: Insight into KAlCuF6 and CuFAsF6.
It is proved that neither the ground state nor the equilibrium geometry of CuF64- complexes in KAlCuF6 and CuFAsF6 is the result of a Jahn-Teller effect and the internal electric field, ER(r), plays an important role in understanding this matter.
Local structure and excitations in systems with CuF64- units: lack of Jahn-Teller effect in the low symmetry compound Na2CuF4.
The present study shows that properties displayed by d9 compounds in low symmetry lattices can hardly stem from a static JT effect, and it is shown that compounds with orthorhombic instability and an internal electric field can have a Δ value comparable to the JT system NaF:Cu2+.
New Ideas for Understanding the Structure and Magnetism in AgF2: Prediction of Ferroelasticity
These results prove that the actual magnetic structure in AgF2 is a direct consequence of vibronic contributions involved in the Jahn‐Teller effect, and show that the system is ferroelastic, a property that is strongly coupled to magnetism in this argentate.
Effect of the Lattice Field on the Electronic Structure and Dynamics of Copper-Hexahydrate in Tutton Salts.
The correlation found here reinforces a recent view that the coupling of the copper complex to the surrounding crystal lattice is the major determinant of these dynamics, and the lattice potentials lack any significant temperature dependency and thus do not appear to be responsible for changes in the EPR patterns.
Explaining the optical spectrum of CrF2 and CuF2 model materials: role of the tetragonal to monoclinic instability.
It is shown that in MF2 compounds, the MF64- complexes are actually compressed in the parent phase but along a different direction, a situation that is however hidden by an additional orthorhombic instability due to a negative force constant of b2g and b3g modes of the cell.

The hydration of Cu2+: Can the Jahn-Teller effect be detected in liquid solution?
The picture of a distorted octahedron for the Cu(II) hexahydrate in aqueous solution, paradigm of the Jahn-Teller effect, is no longer supported and a dynamical view where the different structures exchange among themselves is the picture that better suits the results presented here.
