Overview Overview

Introduction to coordination chemistry and the chemistry of the s-block metals.

(i) Coordination Chemistry: Introduction to transition metals. Historical development of co-ordination chemistry and definitions. Co-ordination numbers and structures of complexes. Nomenclature and isomerism. Bonding in transition metal complexes. Complex formation. Thermodynamic and kinetic stability. Irving-William series.

(ii) Summary of some important concepts such as electronegativity, electronic affinity, ionisation energy and atom/ion sizes. S-block chemistry: Hydrogen (isotopes, occurrence, synthesis, physical properties. H+ and H-, Hydrides, bond energies in the hydrides, hydrogen bonding, hydrogen compounds across the periodic table). Chemistry of the Group 1 and Group 2. Occurrence, uses, physical properties. Halides, oxides, oxoacids and salts. Carbonate and hydrogen carbonates. Fajan's rules, solubility in water and conductivity. Coordination chemistry of group 1 and 2. Structure of the most important ionic compounds (NaCl, CsCl, ZnS, rutile ABX3 solids …). Solid state energetic of group 1-2 salts: Born-Haber cycles, lattice energies and lattice density.
