What type of isomerism is present when positive and negative ions of a salt are complex ions and the two isomers differ in the distribution of ligands in the cation and the anion?

Solution
Coordination isomerism:
“When thepositive and negative ions of a salt are complex ions and the two isomers differ in the distribution of ligands in the cation and the anion, it is called coordination isomerism.”
It arises due to the interchange of ligands between the anionic and cationic species of different metal ions in a complex.
