Learning objectives
Theory: basic concepts of coordination chemistry. Design and use of ligands appropriate for metal coordination. Description of spectroscopic techniques applied to coordination chemistry: eteronuclear NMR, IR and UV-vis spectroscopies.
Laboratory: safety rules, use of common laboratory glassware, preparation of coordination compounds with transition and s-p metal ions (Cu2+, Co2+, Co3+, Zn2+, VO2+, Al3+. Use of spectroscopic techniques for the characterization of the compounds prepared in the laboratoty.
