title: Nitrite reduction mediated by the complex RuIII(EDTA).
abstract: Reported is the first example of a ruthenium(III)-complex, Ru(III)(EDTA) (EDTA(4-) = ethylenediaminetetraacetate), that mediates O-atom transfer from nitrite to the biological thiols cysteine and glutathione, leading to the formation of [Ru(III)(EDTA)(NO(+))](0). However, at pH below 5.0, the coordinated nitrite ion in the [Ru(III)(EDTA)(NO2)](2-) complex undergoes proton-assisted decomposition, resulting in the formation of a [Ru(III)(EDTA)(NO(+))](0) species.
