Knowledge and understanding
Students should be able to:
- Formulate synthetic strategies to target specific ligand types, and predict the properties of resultant coordination complexes and supramolecular species.
- Understand the principles of organometallic chemistry which lead to applications in organic synthesis and catalysis.
- Demonstrate an understanding of the fundamental chemistry and physical properties of the 4f and 5f elements.
- Develop an in-depth understanding of core topics in Inorganic Chemistry
