Octahedral complexes of copper(II) undergo structural distortion (Jahn-Teller). Which one of the given copper(II) complexes will show the maximum structural distortion?
(en – ethylenediamine;H2N−CH2−CH2−NH2)
(en – ethylenediamine;H2N−CH2−CH2−NH2)
[Cu(H2O)6]SO4
[Cu(en)(H2O)4]SO4
cis−[Cu(en)2Cl2]
trans−[Cu(en)2Cl2]
The Correct Option is D
Solution and Explanation
John teller distortion: Any non-linear compound remove its degeneracy to attain the stability.
Extent of John teller distortion depends upon metal ion as well as nature of ligand.
Stronger the ligand, more will be the John Teller distortion and more will be the stability.
Hence, Trans [Cu(en)2Cl2] will exhibit maximum John Teller distortion.
So, the correct option is (D): Trans - [Cu(en)2Cl2].

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
