Vedclass · Answer

(D) Coordination isomerism occurs in compounds containing both cationic and anionic coordination entities where the ligands can be exchanged between the metal centers.For coordination isomerism to exist,both the cation and the anion must be complex ions,and the metal atoms should be different or have different oxidation states/ligand environments.In option $D$,$[Zn(en)_2][Zn(OH)_4]$,both the cation and anion contain the same metal $(Zn)$ and the same oxidation state $(+2)$.Exchanging ligands between these two identical metal centers does not result in a new chemical isomer,as the structure remains effectively the same.Therefore,$[Zn(en)_2][Zn(OH)_4]$ cannot show coordination isomerism.

List-$I$ (Complex)	List-$II$ (Type of isomerism)
$A$. $[Co(NH_3)_5(NO_2)]Cl_2$	$I$. Solvate isomerism
$B$. $[Co(NH_3)_5(SO_4)]Br$	$II$. Linkage isomerism
$C$. $[Co(NH_3)_6][Cr(CN)_6]$	$III$. Ionization isomerism
$D$. $[Co(H_2O)_6]Cl_3$	$IV$. Coordination isomerism
