Oxidation of a [Cu2S] complex by N2O and CO2: insights into a role of tetranuclearity in the CuZ site of nitrous oxide reductase

Author affiliations

Abstract

Oxidation of a [Cu2(μ-S)] complex by N2O or CO2 generated a [Cu2(μ-SO4)] product. In the presence of a sulfur trap, a [Cu2(μ-O)] species also formed from N2O. A [Cu2(μ-CS3)] species derived from CS2 modeled initial reaction intermediates. These observations indicate that one role of tetranuclearity in the CuZ catalytic site of nitrous oxide reductase is to protect the crucial S2− ligand from oxidation.
