Solution
Ambidentate Ligand:
Such ligands have two or more donor atoms but only one donor atom is attached to the metal during complex formation.
For example, NO−2 group has two donor atoms N and O. Only one donor atom is linked to metal as M−ONO or
M−NO2
Also, SCN− has two donor atoms S and N but only one can be linked to the metal such as M−SCN or M−NCS.
Similarly, CN− has two donor atoms C and N but only one can be linked to the metal such as
M−CN or M−NC
