The chelate effect results in the enhanced affinity of chelating ligands for a metal ion compared to the affinity of a collection of similar non-chelating monodentate ligands for the same metal. This, in turn, results in the larger values of overall formation constants for the chelate complexes than their monodentate counterparts. (a) (b) Figure 9.

The chelate effect is caused by the chelating agents, often known as ligands. Moreover, Chelation is used in the chemical industry and medicine and biological field. For detailed information, here’s a Chelation study material curated by the field experts comprising chelate effect, agents, characteristics and uses of Chelation along with all ...
螯合效应_百度百科
螯合效应指出，生成螯合物的反应比生成普通非螯合配合物的反应在能量上更有利。 它主要由两个因素导致，一是熵增作用——螯合反应熵变高过普通配位反应，因需用配体分子数较少；另一则是焓作用——同一多齿配体减少了多个配位点原子间的相互排斥，有利于促进螯合物的生成。 “科普中国”是为我国科普信息化建设塑造的全... 对同一种原子，若形成螯合物比单基配位体形成的络合物（非螯合物）要更加稳定，这种效应称作螯合效应。 螯合物一般以五元环、六元环为最稳 …

Stability, Chelation and the Chelate Effect - gusC
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 example, comparison of the binding of 2,2'-bipyridine with pyridine or 1,2-diaminoethane (ethylenediamine=en) with ammonia.
Thermodynamic evaluation of chelate and cooperativity effects
Jan 1, 1983 · The net chelate effect, Δμ° η, is linearly related both to the number of donor atoms and to the number of chelate rings. The enthalpy and entropy contributions to the chelate effect can also be calculated and critically analysed.

Stability, Chelation and the Chelate Effect
Mar 31, 2015 · 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 example, comparison of the binding of 2,2'-bipyridine with pyridine or 1,2-diaminoethane (ethylenediamine=en) with ammonia.
4.12: The Chelate Effect (and Macrocycle Effect)
Oct 25, 2020 · The chelate effect is the enhanced affinity of a chelating ligand for a metal ion compared to its monodentate ligand counterpart (s). This term comes from the Greek chelos, meaning "crab". A crab does not have any teeth at all, but it does have two claws for tightly holding onto something.
