Ionization Isomers
What is Ionization Isomers?
Ionization isomers are coordination compounds that have the same molecular formula but differ in the ligand coordinated to the central metal atom versus the counter-ion present outside the coordination sphere. For example, [Co(NH₃)₅Br]SO₄ and [Co(NH₃)₅SO₄]Br are ionization isomers: the first releases SO₄²⁻ on dissolution, while the second releases Br⁻. They are distinguished by the different ions produced upon dissolution in water.
