A dinuclear nickel peroxycarbonate complex: CO addition promotes HO release.

Nickel coordination compounds featuring Ni-O bonds are key structural motifs in both bioinorganic and synthetic chemistries. They serve as precursors for organic substrate oxidation and are commonly invoked intermediates in water oxidation and oxygen reduction schemes. Herein, we disclose a series of well-defined dinuclear nickel complexes that, upon treatment with CO and HO, afford the first nickel-bound peroxycarbonate.
