List of ligand abbreviations

Common abbreviations for ligands in chemistry are listed on this page . A ligand is generally understood here as a group of atoms or individual atoms that are coordinated to a central particle. The abbreviations are generally included in the structural formula .

Also amino acids can coordinate as ligands. These can be identified with the three-letter code .
