- Chelating ligands often form more stable complex ions than the corresponding monodentate ligands with the same donor atoms. For example, Ni2+(aq)+6NH3(aq)Ni(NH3)62+(aq)K=3.2108Ni2+(aq)+3en(aq)Ni(en)32+(aq)K=1.61018Ni2+(aq)+penten(aq)Ni(penten)2+(aq)K=2.01019 where en is ethylenediamine and penten is This increased stability is called the chelate effect.
