The learners should be able to apply theories of chemical bonding, reaction mechanism, electronic structure and magnetic properties of coordination complexes to identify the occurrence, active site structure and functions of some transition metal ion containing metalloproteins or enzymes. Learning Outcomes: At the end of the course, the learners should be able to: Identify the principles, structure and reactivity of selected coordination complexes Interpret their electronic spectra and magnetic properties. Utilize the principles of transition metal coordination complexes in understanding functions of biological systems.
