Transition Metal Chemistry and Magnetochemistry 0600-S2-EN-TMCM

Lecture
The main teaching problem is to acquaint students with transition metal chemistry, both in terms of theoretical and utilitarian.
The following content of the curriculum are included: an introduction to the transition metal chemistry; the crystal field theory; the molecular orbital theory; the redox properties of transition metals, nomenclature, isomerism, thermodynamic stability, reactions, kinetics and reaction mechanisms of coordination compounds, visible and infrared spectroscopy of coordination compounds, the use of coordination compounds in catalysis, industrial processes, coordination compounds in biology and medicine, the transition metals compounds in the solid state; non-stoichiometric compounds; solid phase reactions; layered coordination compounds and intercalates; a brief description of dia- and paramagnetism, magnetic properties of d- and f-electron ions, spin equilibria, exchange interactions, magnetic properties of dimers and clusters; new magnetic materials based on coordination compounds; the basics of the EPR phenomenon and its application to study of transition metal compounds.
Laboratory
The aim of the experiments is to extend the knowledge of the synthesis and reactions of transition metal compounds and to acquire research skills of physical-chemical properties of transition metal compounds using a number of measurement techniques, including magnetochemical and EPR measurements.
Synthesis includes complexes of chromium(II), chromium(III) with picolinic, dipicolinic and oxalic acids, chromium(III) organometallic compounds, iron(III), copper(II) and nickel(II) complexes in various solvents.
Problems of experiments take into account: the use of ion exchange chromatography for separation and purification of chromium(III) complexes; the metal to ligand molar ratio determination using a spectrophotometric method; copper(II) as a coordination center; application of chromium(II) compounds; learning of an inert gas atmosphere techniques; determination of the magnetic susceptibility by the Faraday method; high- and low-spin complexes; study and interpretation of the EPR spectra of radicals and transition metal compounds.
