key term - Monodentate

Definition

Monodentate describes a ligand that forms a single bond with a central metal atom or ion in a coordination complex. It can donate only one pair of electrons to the metal center.

5 Must Know Facts For Your Next Test

1. Monodentate ligands have only one donor atom that coordinates to the metal center.
2. Common examples of monodentate ligands include water (H2O), ammonia (NH3), and chloride ions (Cl-).
3. In a coordination complex, monodentate ligands typically result in simpler geometries compared to polydentate ligands.
4. Monodentate ligands can influence the stability and reactivity of the metal complex they coordinate with.
5. The denticity of a ligand is an important factor in determining the overall structure and properties of coordination compounds.
