Pre-requisites before taking this module (or general academic requirements):

CHEM111 CHEM111 Introductory Inorganic Chemistry; CHEM170 Introductory Spectroscopy 

Aims

The aims of the module are:
• To outline how bonding theories (crystal field, ligand field) have been developed by chemists to rationalise important properties of the d–block elements and to introduce the theory underlying the use of appropriate physical and spectroscopic techniques for characterising d–block complexes, and examples of their application.
• To illustrate the chemistry of the transition elements by a detailed study of three d-block triads and introduce the chemistry, and some applications, of complexes in low oxidation states.
• To explain the mechanisms by which transition metal complexes exchange ligands.


Learning Outcomes

(LO1) By the end of the module students should be able to:

• Demonstrate an understanding of transition-metal chemistry
• Show an understanding of the concepts, applications and limitations of the different bonding theories relevant to transition-metal complex chemistry, and be aware of their relative relevance in different chemical contexts.
• Be able to identify key elements of the structures of transition-metal complexes, and apply their knowledge of spectroscopic and physical techniques to work out the correct structure for a complex, given relevant chemical and spectroscopic information.
• Be able to describe the social, economic and technological importance of selected transition elements.
• Understand and be able to describe the significance of the syntheses, characterisation and chemistry of 3d metal complexes
• Understand the origin of the 18-electron rule, its application and the so rt of complexes to which it applies.
• Demonstrate an understanding of the role of ligand field and other factors in determining how metal complexes undergo ligand exchange.
• Appreciate the bonding of different organic fragments to transition metals and how a variety of physical measurements can be used to substantiate these ideas.


Teaching and Learning Strategies

The course will be delivered in three blocks of 50-minute online lectures, 12 on bonding theories, 14 on 3d metal descriptive chemistry and ligand exchange and 10 on low oxidation state chemistry, p-acceptor ligands and the 18-electron rule (these numbers include some revision/exam preparation sessions). These will be supported by eight one-hour problem-based tutorials delivered F2F or online as Covid restrictions allow, comprising formative and summative problem sets.
