Overall aims and purpose
This module aims to provide an in depth study of selected important topics in advanced inorganic chemistry; bio-inorganic chemistry of metalloproteins (structure, function and advanced characterisation) and an appreciation of the diverse chemistry associated with the so-called 'electron deficient' cluster compounds.
(12 lectures) - Bio-inorganic Chemistry - This series of lectures will focus on the chemistry of metal ions in biological systems, particularly on the design of enzyme active sites with regard to their main biological roles. Bulk metals (Na, K, Ca and Mg) will be introduced but the main focus will be on important trace metals (e.g. Fe, Zn and Cu), and key ligand types (O, N and S-based ligands). Characterisation techniques which are applicable to enzyme active sites and special topics (e.g. metal uptake/transport) will also be studied.
(12 lectures) - Structure and shapes of boron hydrides: historical introduction, definitions and terminology, shapes of binary boron hydrides, nomenclature. Bonding in boranes: valence bond approach to B2H6, Linear Combination of Atomic Orbital (LCAO) approach, styx numbers and bonding in boranes. Predicting the topology of boron hydrides: molecular orbital theory for B6H62-, electron counting rules (Wade's rules) as derived from MO theory. Chemistry of typical boron hydrides: preparation and interconversion of boron hydrides, reactions of diborane(6), reactions of decaborane(14). Carboranes: electron counting rules for predicting structures, synthesis of carboranes, mechanisms of interconversions of 1,2-C2B10H12 to 1,7- and 1,12- isomers, metal complexes. 'Naked' main group clusters: polyatomic Zintl anions of Sn, Pb, Bi; application of Wade's rules; polyatomic Bi cluster cations. The isolobal analogy: bonding in octahedral metal complexes; metal-ligand fragments of an octahedron in relation to main group fragments. Metal complexes of boron hydrides: MLx fragments for use in Wade's rules; preparative reactions to form readily available boron hydride anions; metal complexes of anions. High nuclearity carbonyl clusters: total electron counts (TEC) for large metal clusters; capped structures; explanations of the structures observed for large Os, Rh, and Ni/Pt carbonyl clusters.
