CHEM30240 Main Group Chemistry and Bonding

Academic Year 2022/2023

This module is divided into two main sections. The first part focuses on coordination chemistry and properties associated with transition metal complexes. In particular, electron configuration of metals (high and low spin), geometry, trans- and the Jan-Teller effects are discussed. Ligand-metal bonding models are presented along with an introductory to magnetic properties and analysis by electron spin resonance. In the second part of this module, the focus is on crystallography. Topics include: introduction to diffraction; single-crystal versus powder diffraction; single-crystal solution and refinement methods; polymorphism; crystallographic disorder; powder diffraction advantages and drawbacks.

Extra help is available in the form of additional material provided on Blackboard.
