An overview is given of experiments suitable for advanced undergraduates that will introduce them to the preparation and characterization of a bioinorganic model complex. Techniques and concepts emphasized include inorganic synthesis, UV-visible spectroscopy, titrations, heterogeneous catalytic reaction mechanisms, oxidation-reduction reactions, and kinetic and isotope effects. For demonstration purposes, the active site of water oxidation in photosystem II (PSII), the oxygen-evolving complex (OEC), is chosen as a biological metal cluster of interest.
