An important and interesting example of this is the chelating agents—ligands which are able to form two or more coordinate covalent bonds with a metal ion. One of the most common of these is 1,2-diaminoethane (usually called ethylenediamine and abbreviated en.) For metals which display a coordination number of 6, an especially potent ligand is ethylenediaminetetraacetate ion (EDTA).
