jahn teller effect explain axial distortion in perfect octahedral geometry. it is present in d4 high spin d7 low spin and d9 configuration which have odd number of electrons in eg set.a weak jahn teller effect in also present in d7 high spin complex which has odd number of electron in the set

Jahn - Teller effect is not observed in high spin complexes of. Solution : Jahn-Teller effect is tetragonal distortion of octahedral complexes which arises whenever the eg orbitals (dx2-y2 and dz2 orbitals) are unequally occupied (an asymmetrical arrangement of d electrons
