A chelate is a chemical compound composed of a metal ion and a chelating agent. A chelating agent is a substance whose molecules can form several bonds to a single metal ion. In other words, a chelating agent is a multidentate ligand. An example of a simple chelating agent is ethylenediamine.ethylenediamine. A single molecule of ethylenediamine can form two bonds to a transition-metal ion such as nickel(II), Ni 2+ .n other words, a chelating agent is a multidentate ligand.
