Study Notes
Complexation in Physical Pharmaceutics
- A ligand is a molecule or ion that donates one or more electron pairs to a central atom or ion to form a complex.
Complexation Definition
- Complexation is a process in which a central atom or ion, typically a metal ion, is bonded to one or more ligands, resulting in a complex species.
Altered Properties of Complexing Species
- After complexation, the physical and chemical properties of the complexing species are altered, including changes in solubility, stability, and reactivity.
Bonds Involved in Complex Formation
- Coordination bonds, also known as dative covalent bonds, are involved in complex formation, where the ligand donates one or more electron pairs to the central atom or ion.
Coordination Complex
- A coordination complex, also known as a complex ion, is a complex species formed by the coordination of one or more ligands to a central atom or ion, resulting in a stable, three-dimensional structure.
