Biological systems including microorganisms such as bacteria use enzymes to survive on the earth. Most enzymes contain metal ions as a functional active center. We are interested in studying the magnetic properties of such inorganic systems in order to better understand their unique properties. In our laboratory, we focus on synthesis, crystal structures, and the magnetic properties of metal complexes having some relevance to biological metallo-enzyme systems at the in a molecular level. Especially, oligo- and polynuclear metal systems such as Mn4complex at the Oxygen Evolution Center within the Photosystem II of green plants are most interesting for study, showing unusual molecular structures and magnetic properties. We use single-crystal X-ray diffractometer, SQUID susceptometer, IR and UV-vis-NIR spectrometers as our major tools for research.
