Complex formation between derivatives of pyridine N-oxides and iron(III) nitrate in aqueous medium

Resumo

Donor-acceptor complexes of derivatives of pyridine N-oxides with iron(III) nitrate have been studied. Their stability constants in water and in aqueous acetone have been determined. The complexes stability increases upon heating, at decreasing solvent polarity, and in the presence of the substituents in the N-oxide ring.
