Ligand. Definition. noun, plural: ligands. (1) A molecule, ion or atom bonded to the central metal atom of a coordination compound. (2) Any substance (e.g. hormone, drug, functional group, etc .) that binds specifically and reversibly to another chemical entity to form a larger complex.Supplement. A ligand may function as agonist or antagonist.1) A molecule, ion or atom bonded to the central metal atom of a coordination compound. (2) Any substance (e.g. hormone, drug, functional group, etc .) that binds specifically and reversibly to another chemical entity to form a larger complex.
The ions or molecules that bind to transition-metal ions to form these complexes are called ligands (from Latin, to tie or bind). The number of ligands bound to the transition metal ion is called the coordination number.oordination compounds, such as the FeCl 4 - ion and CrCl 3 6 NH 3, are called such because they contain ions or molecules linked, or coordinated, to a transition metal. They are also known as complex ions or coordination complexes because they are Lewis acid-base complexes.
