Solution
The correct option is D All of the above.
In complexes when the cation and anion both are complex ions, there may be exchange of ligands between these two complex ions resulting in coordination isomers. In the pairs of these isomers, the central metal cation in the two coordination sphere can be same or different.
In option (a), all ethylenediamine and cyanide ligands are interchanged.
In option (b), two Cl− ligand is interchanged from one coordination entity to other.
In option (c), two ammonia and cyanide ligands are interchanged between the coordination entity.
Hence, option (a), (b) and (c) represents coordination isomers.
