WebAug 15, 2024 · The formation constants are formulated as ligand exchange reactions with aqua ligands being displaced by new ligands ( NH3 or en) in the examples above. Chelate complexes are more stable than the analogous complexes with monodentate ligands. The stability of a chelate complex depends on the size of the chelate rings. Chelation is a type of bonding of ions and 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. These ligands are called chelants, chelators, chelating agents, or sequestering agents. They are usually organic compounds, but this is not a necessity, as in the case of zinc and its use as a maintenance therapy to prevent the absorption of copper in people with Wilson's …
WebCoordination compounds containing polydentate ligands are called chelates (from Greek chele, “claw”), and their formation is termed chelation. Chelates are particularly stable and useful. An example of a typical chelate is bis (1,2-ethanediamine)copper (2+), the complex formed between the cupric ion (Cu 2+) and the organic compound ...
