bidentate
(adjective)
Of a ligand, forming two separate chemical bonds to a coordinating metal ion.
Examples of bidentate in the following topics:
-
Coordination Number, Ligands, and Geometries
- A ligand that binds through two sites is classified as bidentate, and three sites as tridentate.
- A classic bidentate ligand is ethylenediamine, which is derived by the linking of two ammonia groups with an ethylene (-CH2CH2-) linker.
- For example, trans-spanning ligands are bidentate ligands that can span coordination positions on opposite sides of a coordination complex.
-
Chelating Agents
- In (1), the bidentate ligand ethylenediamine forms a chelate complex with the copper ion.
-
Isomers in Coordination Compounds
- The symbol Λ (lambda) is used as a prefix to describe the left-handed propeller twist formed by three bidentate ligands.
