Methimazole (2-mercapto-1-methylimidazole, MMI) and its pentacyanoferrate(II) complex have been characterized by means of UV/Vis, Raman and NMR spectroscopy. The reaction of MMI with aquapentacyanoferrate(II), [Fe(CN)5(H2O)]3−, in buffered aqueous solutions yielded the [Fe(CN)5(MMI)]3− complex. It was found that only thione tautomer of MMI coordinates to the iron(II). The exceptionally stabile and inert complex was produced.
