Chelate effect and its thermodynamic origin
WebTo understand the thermodynamic origin, ... As with the chelate effect, the precise origin of the effect is still a topic of discussion, but the phenomenon is clear (Table 4). For a given combination of donors, the most stable complexes are likely to be formed with a macrocyclic ligand, subject to the constraint that the optimal metal–ligand ...

WebMar 31, 2015 · The Chelate Effect. The chelate effect can be seen by comparing the reaction of a chelating ligand and a metal ion with the corresponding reaction involving comparable monodentate ligands. For … WebMay 1, 2024 · The kinetic chelate effect is a result of a slower first dissociation step and faster re-association step relative to that of a monodentate ligand. The complete dissociation of a bidentate ligand, for example, would require two dissociation steps (see first reaction in figure below). It is the first dissociation step that is slower in a ...
