Isomerism of coordination compounds - Structural Isomerism

STRUCTURAL ISOMERISM

                     

  

       1.     Structural Isomerism:

         a)    Ionization Isomerism: It occurs when the ligands in the complex can be exchanged with the anions present outside the coordination sphere.

Example:

                                    

          b)    Hydrated isomerism: it occurs when different number of water molecules are present inside and outside the coordination sphere.

Example:

                      

   

      

         c)     Linkage Isomerism: Occurs in ambidentate ligands.

Example:

         d)    Coordination Isomerism: It occurs when both cations and anions are complexes in such cases the ligand or the central metal atom or both can be exchanged.

Example:
