S-nitrosation of the coordinated thiolate of dinitrosyl iron complexes (DNICs) to generate S-nitrosothiols (RSNOs) was demonstrated. Transformation of [{(NO)(2)Fe(μ-StBu)}(2)] (1-tBuS) into the {Fe(NO)(2)}(9) DNIC [(NO)(2)Fe(StBu)(MeIm)] (2-MeIm) occurs under addition of 20 equiv of 1-methylimidazole (MeIm) into a solution of 1-tBuS in
