On this course, we will explore the coordination chemistry of first row transition metals, focusing on the role of d-orbitals and d-electrons in their chemistry. We will discuss the synthesis and reactivity of basic coordination complexes and explore the possibilities for isomerism. Crystal Field Theory will be used to explain the splitting of the d-orbitals in appropriate geometries, and the effects of both ligand and metal on the extent and nature of the splitting will be included. An introduction to the consequences of the d-orbital splitting on complex properties will be given, focusing on trends in ionisation energy, preferred geometries, oxidation states, high spin and low spin complexes and the magnetic properties of transition metal ions.
When looking at the structures of transition metal complexes we will examine their common coordination numbers and geometries. Theories of bonding in coordination compounds are now advanced but we will restrict ourselves to some basic models. An understanding of the bonding within coordination compounds is crucial if we are to successfully explain their chemistry, in particular their thermodynamic, spectroscopic, and magnetic properties. We will turn our attention to isomerism in coordination chemistry before discussing the stability of coordination compounds in aqueous solution. Underpinning all the discussions described above will be a consideration of the (often dramatic) effects of varying the ligand and how these effects can be harnessed to control the chemical and physical properties of coordination complexes.
