Ligand

Cobalt complex HCo(CO)4 with five ligands
Metal–EDTA complex, wherein the aminocarboxylate is a hexadentate chelating ligand.
Cobalt(III) complex containing six ammonia ligands, which are monodentate. The chloride is not a ligand.

In coordination chemistry, a ligand is an ion or molecule (functional group) that binds to a central metal atom to form a coordination complex. The bonding between metal and ligand generally involves formal donation of one or more of the ligand's electron pairs. The nature of metal–ligand bonding can range from covalent to ionic. Furthermore, the metal–ligand bond order can range from one to three. Ligands are viewed as Lewis bases, although rare cases are known to involve Lewis acidic "ligand."
