These complexes contain a central atom or ion, often a transition metal, and a cluster of ions or neutral molecules surrounding it.

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).
