what is ambidentate ligand

An ambidentate ligand is a type of ligand that has two different donor atoms and can attach to a central metal atom through either of the two donor atoms during complex formation. This means that an ambidentate ligand can bond to the central atom in two places, but not at the same time. Common examples of ambidentate ligands include the thiocyanate ion (SCN-) and the nitrito ion (NO2-)
