This module provides a deeper understanding in the Chemistry of d-block. Transition metal (TM) elements form a plethora of complexes with properties that range from drug anti-cancer activity to catalytic properties in process industry. The stereochemical and bonding properties of TM complexes form key to their function. The course builds on the concepts introduced in year 1 and gives a deeper understanding in concepts of structure, bonding, stereochemistry and their relationships to provide a full picture of the features of the complexes. The course also brings familiarity with the basic spectroscopic properties of TM complexes and organometallic chemistry is firstly introduced. The final section of the course covers trends in both physical and chemical properties of transition metal elements and ions across and down the d-block, and discusses common oxide and fluorides including an introduction to their solid state structures. This section concludes with an introduction to metal-metal bonding in transition metal compounds and the influence that this has on electronic and magnetic behaviour.
