Example of chelate ligand
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 … WebA chelating ligand is also known as a chelating agent. A chelating ligand holds the metal ion rather like a crab’s claw would hold a marble. Figure 19.15 showed one example of a …

Complexes containing chelate rings are more stable than complex without rings. This is called the chelate effect. Examples: [Co(en)3]3+ is more stable than [Co(NH3)6]3+ where Ethylenediamine (en) is an … WebThe chelate effect The bidentate or polydentate ligands form five or six-membered coordinate bonds so that a ring structure is formed, with the metal centre usually forming more stable complexes than the others. For example, cadmium ions, [Cd(H2O)4]2+ with methylamine (CH3NH2). Macrocyclic effect. Macrocyclic ligands are multi-dentate.
WebA ligand molecule with more than one donor atom is a called a polydentate ligand. These are given specific names, depending on how many donor atoms they contain. Bidentate Ligands. Bidentate ligands have two atoms capable of binding to a central metal atom or ion. Ethane-1,2-diamine (shown in the image) is an example of a bidentate ligand.
