N2 - The recent discovery of the C-NONOate moiety ([X{N2O2}]−; diazeniumdiolate) as a new class of siderophore functional group necessitates further examination of its coordination chemistry. The bidentate η2-O,O binding mode of the C-NONOate moiety is well-established. We have synthesized and characterized, by X-ray crystallography, the first monodentate η1-O binding mode of a C-NONOate group to any metal, namely that of (OEP)Ru(NO)(η1-ONN(t-Bu)O). The compound exhibits an irreversible first oxidation in CH2Cl2 at a Pt electrode. Protonation with triflic acid results in the formation of N2O, presumably from the direct protonation of the C-NONOate ligand.
