Advantages

First isolation and characterization of an [Fe2S2]-type complex bearing a cis-μ-η1:η1-NH═NH subunit

μ-Nitride undergoes stepwise proton-coupled electron transfer for efficient ammonia release or direct hydrogenation with H₂ for high-yield ammonia formation

Catalytic N2 reduction to silylamines achieved with [Fe2S2]-type complexes via ligand modulation
