Triazenide-supported [Cu₄S] structural mimics of Cu_Z that mediate N₂O disproportionation rather than reduction.

ABSTRACT: As part of the nitrogen cycle, environmental nitrous oxide (N₂O) undergoes the N₂O reduction reaction (N₂ORR) catalyzed by nitrous oxide reductase, a metalloenzyme whose catalytic active site is a tetranuclear copper-sulfide cluster (Cu_Z). On the other hand, heterogeneous Cu catalysts on oxide supports are known to mediate decomposition of N₂O (deN₂O) by disproportionation. In this study, a Cu_Z model system supported by triazenide ligands is characterized by X-ray crystallography, NMR and EPR spectroscopies, and electronic structure calculations. Although the triazenide-ligated Cu₄(μ₄-S) clusters are closely related to previous formamidinate derivatives, which differ only in replacement of a
