Abstract

Nitrosylation of the chelate-thiolate-containing dinitrosyliron complex (DNIC) [(S(CH2)3S)Fe-(NO)2]- triggers nitric oxide (NO) activation to generate the homoleptic nitrosyl {Fe(NO)2}9 DNIC [Fe(NO)4]- (1) made up of two nitroxyls (or two NO anions) attached to a delocalized {Fe(NO) 2}9 motif. The significantly longer N3-O3/N4-O4 [1.380 (12) and 1.280 (12) Å] and Fe1-N3/Fe1-N4 [2.008 (11) and 2.045 (10) Å] bond distances reflect that N3-O3 and N4-O4 of complex 1 may act as the nitroxyl-coordinated ligands. That is, the electronic structure of the DNIC 1 is best described as a {Fe(NO)2}9 motif coordinated by two nitroxyl (NO-) ligands.
