Ligand may contain one or more than one donor atoms. If only one donor atom is present in its molecule which can coordinate then it is unidentate. For example, H2O, NH3.

If the ligand contains two donor atoms placed in a way that a five or six membered ring is formed with the metal ion then it is called as bidentate. Example is oxalate ion.
