Course objectives
This course utilizes basic knowledge of chemistry of metal complexes gained in lectures on inorganic chemistry and develops advanced topics of bonding in transition metal complexes, their spectroscopic and magnetic propertes, thermodynamic stability and kinetic behavior in chemical reactions.
Learning outcomes
Upon completing this course, students will be able to:
- describe bonding in transition metal complexes by ligand field theory and molecular orbital theory
- explain behavior of metal complexes in UV-vis, NMR, EPR, Moessbauer spectra
- describe magnetic properties of metal complexes
- understand thermodynamic stability and kinetic behavior of complexes in chemical reactions
Syllabus
  • Introduction. Historical Perspective – A. Werner. Transition metals and d-electron configurations, a coordination complex, metal-ligand bonding, the coordinate bond and Lewis Acid-Base interactions. Types of ligands and their coordination modes. Isomerism: geometric, structural, constitutional, linkage.
  • Bonding in Metal Complexes. d-orbitals, Ligand Field Theory for octahedral and tetrahedral complexes. Effect of inter-electron repulsion – high and low spin electron configurations, pairing energy. Spin-only magnetic moments. Molecular orbital description, MO Theory of octahedral complex σ bonds. Ligand field splitting in octahedral complexes (sigma- and pi-bonding). Factors determining the ligand field splitting, spectrochemical series of ligands and metals - sigma-donors, pi-donors, pi-acceptors (weak and strong field ligands), pi-backbonding. Jahn-Teller effects.
  • Thermodynamics across the first row transition series– Lattice field stabilization energies, Lattice energies, Hydration energies, Variations in ionic radii. Stability constants. Irving-Williams series. Stability of Metal Complexes - Kinetic and Thermodynamic stability. Stepwise formation constants. Chelate and macrocyclic effects.
  • Geometries of Metal Complexes. Tetrahedral molecular orbital diagram and ligand-field splitting. Square planar geometry, trigonal bipyramidal geometry. Role of ligand field vs ligand size in determining complex geometry. Less common oxidation states, mixed-valence complexes.
  • Electronic Spectroscopy. The Colors of TM Complexes. Term symbols. Electronic spectra for transition-metal complexes. Interelectronic repulsion and the nephelauxetic series. Orbital, Laporte and spin selection rules. The Frank-Condon principle. Charge transfer transitions (ligand to metal, metal to ligand and intervalence).

  • Magnetochemistry. Spin crossovers. Spin frustration. Molecular magnets. NMR and EPR spectroscopy of transition metal complexes.
  • Transition Metals in Low Oxidation States. Carbonyl complexes and organometallic chemistry. MO diagram for CO, 18 electron rule, pi-backbonding. Vibrational spectroscopy of carbonyl compounds.
