Isomerism
Which type of isomerism is shown by [Co(NH₃)₅NO₂]Cl₂ and [Co(NH₃)₅ONO]Cl₂?
Select the correct option:
Solution
Linkage isomerism
Linkage Isomerism arises in coordination compounds containing ambidentate ligands.
- An ambidentate ligand is one that can coordinate to the central metal through two different atoms.
- The NO2− ion can coordinate either through the nitrogen atom (M−NO2, nitro) or through the oxygen atom (M−ONO, nitrito).
- Since these two complexes differ only in the atom through which the nitrite ligand is linked to the Cobalt, they are linkage isomers.
