Nitrogen Binding and Fixation using Iron-Sulfur Complexes

The enzyme nitrogenase reduces atmospheric N2 using an unusual iron-sulfur cluster, the FeMoco, which has an unprecedented carbide-centered structure. In an effort to understand the fundamental behavior of iron sites like these that are coordinated by sulfur and carbon, we have synthesized coordination compounds with these biologically relevant donors and studied their structures, spectroscopy, and reactivity. This seminar will discuss the mechanisms of formation and reactivity of new biomimetic Fe-N2 complexes, and explore the implications toward nitrogenase reactivity.

 Light refreshments will be served at 3:50 at The Coffee Lab, 510-643-0572
