Prof. D.K.Kariuki, Department of Chemistry, University of Nairobi
, COURSE OUTLINE
Pre-requisite: SCH 101, 201, 205, 301
General properties of transition elements: electronic configuration, variable oxidation
states, catalysis, coloured compounds and complexes. Transition metal complexes:
Ligands, nomenclature, coordination number, effective atomic number (EAN)
stereochemistry, isomerism, Chelate and chelate effect. Bonding of coordination
complexes: Valence bond theory, crystal field theory complexes, crystal field stabilization
energy, spectrochemical series, Orgel and Tanabe- Sugano diagrams. Ligand field
theory: Interelectronic parameters, Nephelauxetic effect. Molecular orbital theory:
Complexes with and without π orbitals. Steric effects: Tetragonal distortion, square planar
and the Jahn Teller effect. Electronic spectra: d-d transitions, charge transfer, selection
rules, colours of different complexes. Effect of d orbital splitting: Ionic radii and
thermodynamic factors. Magnetic properties of transition metal complexes. Some
application and uses of selected examples of useful coordination compounds.
