Chelate effect and its thermodynamic origin
WebChelating ligands and the chelate effect have been known for a long time, and have been covered in a wide selection of texts. This increase in stability of coordination compounds, which results from chelate ring formation, has been attributed to both to an increase in bond strength resulting from formation of the ring, and to a statistical effect associated with … WebSep 27, 2024 · 5.11: Chelate and Macrocyclic Effects. Ligands that contain more than one binding site for a metal ion are called chelating ligands (from the Greek word χηλή, chēlē, meaning "claw"). As the name implies, chelating ligands have high affinity for metal ions relative to ligands with only one binding group (which are called monodentate ...

WebJul 16, 2024 · The chelate effect is generally agreed to be a thermodynamic effect caused by the change in entropy upon binding of a bidentate ligand. Consider a coordination complex, [M]L 2, where L = a standard monodentate ligand. If we now add a bidentate ligand, two monodentate ligands are released. The ligand substitution reaction in the … WebDec 1, 2003 · Complexes of this nature exhibit an enhanced thermodynamic and kinetic stability from the chelate effect [57], arising from an enthalpy gain due to coordinate …
