Studies on Schiff Base Complexes (V)——Reaction of Fe(Salen)NO3 with Nitrite

Abstract

Abstract: The reaction of Fe(Salen)NO₃ with nitrite in DMFwas studied by UV-visible,¹H NMR, and cyclic yoltammetry.The UV-visible results show that there are no isosbestic points in all the range of nitrite concentrations, indicating that more than two species are present at equilibrium.The NMRspectrum gives a feature of high-spin property.The E_1/2 values depended on the concentration of nitrite, shifting slightly to more negative potentials as the nitrite concentration was increased.When the scanning rate was increased, the Fe³⁺/Fe²⁺ reduction wave split into two waves, also indicating that more than two different species are present at eauilibrium.

Key words: Fe(Ⅲ), Schiff base complexes, Cyclic voltammetry, Nitrite anion
