Ambidentate ligand and their examples
An ambidentate ligand has two different donor atoms and it can link to central metal in a complex through either of them.
Examples of ambidentate ligands
(i) NO−2is an ambidentate ligand. It can coordinate to a central metal atom/ion either through nitrogen or oxygen.
(ii) SCN− is another ambidentate ligand. It can coordinate to a central metal atom/ion either through nitrogen or sulphur.
Linkage isomerism
Linkage isomerism is the existence of coordination compounds that have the same chemical formula but differ in the way ligand is linked to the metal ion.
Thus, the isomerism shown when ambidentate ligands are attached to central metal ion is “linkage isomerism”.
