Chelate | Chelating Agents, Complexes & Compounds | Britannica
WebChelate, any of a class of coordination or complex compounds consisting of a central metal atom attached to a large molecule, called a ligand, in a cyclic or ring structure. An example of a chelate ring occurs in the ethylenediamine-cadmium complex: The ethylenediamine ligand has two points of.
Chelation - Wikipedia
WebChelation is a type of bonding of ions and the molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate (multiple bonded) ligand and a single central metal atom. [1] [2] These ligands are called chelants, chelators, chelating agents, or sequestering agents.
