What type of isomerism exists in compounds containing two or more complexes, each of which contains a different set of ligands that can in principle be replaced with a ligand of the other complex?

The correct answer is Coordination isomerism.

Key Points

• Coordination isomerism
  • ​A type of structural isomerism known as coordination isomerism occurs when the coordination complex ion's makeup changes.
  • The overall ligand to metal ratio in a coordination isomer doesn't vary, but the ligands bound to a particular metal ion do.
  • Instances of a whole series of coordination isomers call for two or even more metal ions.
  • The exchange of one or more ligands between the cationic complex ion and the anionic complex ion is known as coordination isomerism, and it happens in compounds that have complex anionic and cationic components.

Additional Information

• Two or more coordination compounds having a difference in composition within the coordination sphere are said to be coordination isomers.
• This kind of isomerism is caused by the exchange of ligands between anionic and cationic entities of various metal ions that are present in the complex.
• Coordination isomerism, which can be thought of as an exchange of some ligands from the cation to the anion, occurs in compounds that contain complex cationic and anionic components.
• As a result, two complicated chemicals that have opposite charges one negative and the other positive are linked together.
