The Lu group creates and studies metal-metal bonding between two first-row transition metals and between a transition metal and a main group metal. Synergistic combinations of different metals can generate hybrid "metals" that exhibit original properties and/or unique reactivities. We are broadly interested in developing these bimetallic complexes for small-molecule catalysis (e.g., dinitrogen to amine), where using non-precious metals is sensible from economical and sustainability standpoints.
