Hint: The concept of isomerism occurs when two or more molecules have the same chemical composition but different chemical structures. Isomers are chemical compounds with similar chemical equations that vary in properties and atom structure in the molecule.

Complete answer:
Ionisation isomerism refers to compounds that produce different ions in solution while having the same composition. When the counter ion in a complex salt is still a possible ligand, it will displace a ligand, which can then become the counter ion, resulting in isomerism. Except for a ligand that has swapped positions with an anion or neutral molecule that was originally outside the coordination complex, ionisation isomers are indistinguishable.
Ionization isomers are coordination complexes in which the inner and outer coordination spheres have separate ligands. Since the chloride and nitrite ligands have been swapped and are ionisation isomers in the above complex.
Hence, $[Co(N{H_3})4C{l_2}]N{O_2}$ and $[Co(N{H_3})4Cl(N{O_2})]Cl$ exhibit Ionisation isomerism.

Isomers are chemical compounds that have the same chemical composition but vary in structure. They're crucial in air pollution chemistry because even minor structural variations will result in significant chemical and physical differences. As a result, isomers can have differing hemodynamic properties and toxicities.
