monodentate

Examples of monodentate in the following topics:

• Chelating Agents

  • Chelate complexes are contrasted with coordination complexes composed of monodentate ligands, which form only one bond with the central atom.
  • The chelate effect describes the enhanced affinity of chelating ligands for a metal ion compared to the affinity of a collection of similar nonchelating (monodentate) ligands for the same metal.
  • In (2), the two monodentate methylamine ligands of approximately the same donor power (the enthalpy of formation of Cu—N bonds is approximately the same in the two reactions) forms a complex.
  • The effect increases with the number of chelate rings, so the concentration of the EDTA complex, which has six chelate rings, is much higher than a corresponding complex with two monodentate nitrogen donor ligands and four monodentate carboxylate ligands.

• Coordination Number, Ligands, and Geometries

  • Monodentate ligands include virtually all anions and all simple Lewis bases.

• Naming Coordination Compounds

  • Multiple occurring monodentate ligands receive a prefix according to the number of occurrences: di-, tri-, tetra-, penta-, or hexa.
