NettetJahn–Teller effect explains that the electronic state with the lower symmetry is stabilized, due to the release of the degeneracy. In general, 3d orbitals in the octahedral environment split into two degenerated orbitals such as t 2g orbitals (3d xy, 3d yz, and 3d xz) and e g orbitals (3d x 2 − y 2 and 3d z 2).For example, in La 2 CuO 4 perovskite, the double … NettetConsequences of Jahn-Teller Distortion . Stability of Cu 2+ Complexes: For a given ligand, the relative stabilities of complexes of dipositive metal ions of first transition series is in order Ba 2+ < Sr 2+ < Ca 2+ < Mg 2+ < Mn 2+ < Fe 2+ < Co 2+ < Ni 2+ < Cu 2+ > Zn 2+ This is called Irving-William Series. The extra stability of Cu 2+ complexes is due to …
