Abstract

Nitrous oxide (N₂O), a widespread greenhouse gas, is a thermodynamically potent and environmentally green oxidant that is an attractive target for activation by metal centers. However, N₂O remains underutilized owing to its high kinetic stability, and the poor ligand properties of this molecule have made well-characterized metal-N₂O complexes a rarity. We now report a vanadium-pyrrolide system that reversibly binds N₂O at room temperature and provide the first single-crystal X-ray structure of such a complex. Further characterization by vibrational spectroscopy and DFT calculations strongly favor assignment as a linear, N-bound metal-N₂O complex.
