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.

WebJul 3, 2019 · By. Anne Marie Helmenstine, Ph.D. Updated on July 03, 2019. A chelate is an organic compound formed when a polydentate ligand bonds to a central metal atom. Chelation, according to the IUPAC, involves the formation of two or more separate coordinate bonds between the ligand and central atom.

WebJul 30, 2023 · The word chelating, derived from the Greek chele, “claw,” describes the pincer-like way in which such a ligand can grab a metal ion. A chelating agent which forms several bonds to a metal without unduly straining its own structure is usually able to replace a similar simpler ligand.

A metal ion in solution does not exist in isolation, but in combination with ligands (such as solvent molecules or simple ions) or chelating groups, giving rise to complex ions or coordination compounds.
WebA 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.
1.5: The Chelate Effect - Chemistry LibreTexts
WebIt can bind to a metal via two donor atoms at once. Bidentate binding allows a ligand to bind more tightly. Tridentate ligands, which bind through three donors, can bind even more tightly, and so on. This phenomenon is generally called the "chelate effect." This term comes from the Greek chelos, meaning "crab."
