Question

what is ligant?what are different types of ligants?

Answer 1

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.





Types of Ligands. Unidentate ligands: Ligands with only one donor atom, e.g. NH3, Cl-, F- etc. Bidentate ligands: Ligands with two donor atoms, e.g. ethylenediamine, C2O42-(oxalate ion) etc. Tridentate ligands: Ligands which have three donor atoms per ligand, e.g. (dien) diethyl triamine.
