A multidentate ligand which combines with a metal ion through two or more atoms on the ligand simultaneously is called a cheldting agent. The resulting complex is called a chelate compound..Consider the example of copper glycinate complex where two glycinates ' are combined with one copper ion as shown below:
Such glycinate ion is joined through N and 0 to the copper ion simultaneously. Hence glycinate is acting as chelating agent.
