WebAny ligand that bonds to a central metal ion by more than one donor atom is a polydentate ligand (or “many teeth”), because it can bite into the metal center with more than one bond. The term chelate (pronounced “KEY-late”) from the Greek for “claw” is also used to describe this type of interaction. Webdefines the chelate or complex bond. When there is only one point of attachment, a complex is formed with a unidentate bond, while more than one point of attachment in which a heterocyclic ring forms refers to bidentate, tridentate, and multidentate chelate bonds (Figure 3). This heterocyclic ring formation is a defining characteristic of a ...
