Which type of isomerism is shown by coordination compounds that have the same molecular formula but differ in the ligand attached to the central metal atom through different donor atoms?

💡 Solution & Explanation

Linkage isomerism occurs in coordination complexes that contain ambidentate ligands, which can bond to the central metal atom through two different donor atoms such as the nitro and nitrito groups. Other phenomena like ionization isomerism involve the interchange of ions between the coordination sphere and the ionization sphere outside the complex. This structural nuance is critical in coordination chemistry because different bonding atoms alter the physical and spectroscopic properties of the resulting compound.
