RankGuru · Accepted Answer

**Coordination Isomerism** occurs in salts where both the cation and anion are coordination complexes.
- It arises from the interchange of ligands between the cationic and anionic metal centers.
- In the first salt, $NH_3$ is with $Co$ and $CN$ is with $Cr$.
- In its isomer, $NH_3$ is with $Cr$ and $CN$ is with $Co$.
- They share the same empirical formula but have different identities of the complex ions.
