Bidentatliganden
Bidentatliganden, also known as bidentate ligands, are molecules that can form two coordinate bonds with a central metal atom. This means they have two donor atoms, typically heteroatoms like nitrogen, oxygen, or sulfur, that can simultaneously attach to the metal. The term "bidentate" originates from the Latin "bi" meaning two, and "dens" meaning tooth, referencing the two points of attachment. This ability to bind at two positions leads to the formation of a chelate ring, a stable five- or six-membered ring structure encompassing the metal ion.
Chelation significantly enhances the stability of metal complexes compared to those formed with monodentate ligands (ligands
