| Description:
| Aims: To provide an introduction to selected aspects of main group chemistry with particular reference to the heavier p-block elements. To provide a basic knowledge of advanced methods for structure determination. Learning Outcomes: After studying this unit, students should be able to: * Describe the properties and factors effecting stability and reactivity of heavy p-block containing compounds; * Understand the fundamental chemistry of metal compounds containing metal-carbon σ- and π-bonds; * Interpret and make calculations based on simple X-ray diffraction pattern. Skills: Numeracy (F, A); Problem solving (T, F, A); Oral communication (F). Content: The nature and properties of selected p-block element containing compounds (Interhalogen complexes, cationic/anionic halogen and chalcogen systems). Chemistry of the noble gases. The role of d-orbitals in main group element bonding (3-centre 4-electron bonding vs d-orbital participation). P-block ring systems (BN, SN, SeN and PN). Classification of organometallics, general aspects of stability structure and bonding The history, synthesis, structure, bonding and reactivity of main group organometallics (e.g. organolithiums, organomagnesiums and organoaluminiums). The application of selected of main group organometallic compounds. Transition metal organometallics - nomenclature, electron counting. Metal carbon σ- and π bonding. Overview of X-ray generation and use of filters. Crystal classes, lattices and unit cells. Bragg's Law. Uses of powder diffraction. |
