Context:
Describe the relationship to any other modules with which the new module has a
close connection and any prerequisite relationships.
This module follows on from the transition metal component of Year 1 CH160. The one-electron
(orbital) picture is extended to the many-electron (Russell-Saunders) regime for d states in cubic
symmetry. Qualitative electric-dipole selection rules for first-row metal complexes. Totally new
material on organometallic chemistry is discussed leading to an appreciation of the bonding
modes of most ligand types and a brief introduction to their reactivity.

CH160
Post-requisites
CH266

Syllabus:
Give an outline of the syllabus for the module.
The module will be divided into a number of different components, as outlined below.
Group theory
Recognition of symmetry elements. Identification of point groups. Elementary uses of
character tables such as assigning appropriate symmetry labels to molecular orbitals.
d-d spectroscopy of cubic metal complexes
d-d interelectron repulsion. Microstates and many-electron term symbols for d2. Term
symbols for remaining d configurations. Term splittings in cubic symmetry. Qualitative
electric-dipole selection rules. Selected examples.
Compound formation: thermodynamic considerations
Stepwise and overall formation constants; extension of concepts developed in CH160
Substitution reations
Classification scheme, A, D, I. Activation parameters and reaction profiles. Solvent
exchange rates and relationships to d configurations/spin states/LFSE. Ligand substitution at
octahedral complexes – Eigen-Wilkins mechanism and its associated rate law. Ligand
substitution at square planar centres. Rate laws. Trans effects and trans influence.
