While the majority of industrial catalytic reactions occur on heterogeneous surfaces, attempts to model these processes with molecular clusters have traditionally been made with strong field ligands that do not accurately portray the electronic structure of a metal surface. This talk describes the use of redox active ligands in binucleating macrocycles in an attempt to more accurately mimic the electronic and geometric properties of metal surfaces. A bridging dinitrogen complex reminiscent of alpha-N2 binding on the Mittasch catalyst has been synthesized through chemical reduction of a dicobalt macrocycle. This talk includes the characterization of these N2-bound macrocyclic complexes and their reactivity toward dinitrogen reduction.
