WebThese ligands are mentioned as multidentate or polydentate ligands, however there are several different forms. Identification of a unidentate ligand as compared to bidentate, polydentate, and chelating ligands. The number of locations at which ligands are linked to, or bonded to, the metal centre is the commonest means of classifying them. Denticity (represented by κ) refers to the number of times a ligand bonds to a metal through noncontiguous donor sites. Many ligands are capable of binding metal ions through multiple sites, usually because the ligands have lone pairs on more than one atom. Ligands that bind via more than one atom are often termed chelating. A ligand that binds through two sites is classified as bidentate, and three sites as tridentate. The "bite angle" refers to the angle between the two bon…
