Spectroscopic Studies of Methimazole Reactivity toward the Aquapentacyanoferrate (II)‎ Ion in Aqueous Solutions

الملخص EN

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.
