Jahn Teller Distortion in Complexes
- Jahn Teller distortion is a phenomenon that occurs in octahedral complexes with degenerate electronic states. It is caused by the interaction between the electrons in the degenerate orbitals and the molecular vibrations, leading to a distortion in the complex.
Complexes with Jahn Teller Distortion
- Among the given complexes, K4[Fe(CN)6], K3[Co(CN)6], and K4[Mn(CN)6], Jahn Teller distortion is expected only in K4[Mn(CN)6].
- K4[Fe(CN)6] and K3[Co(CN)6] have d6 electronic configuration which is not degenerate and hence do not show Jahn Teller distortion. On the other hand, K4[Mn(CN)6] has d5 electronic configuration which is degenerate. Hence, it shows Jahn Teller distortion.
In conclusion, Jahn Teller distortion is a phenomenon that occurs only in octahedral complexes with degenerate electronic states. Among the given complexes, K4[Mn(CN)6] is the only one with degenerate electronic states and hence shows Jahn Teller distortion.
