Studies on some iron complexes using Moessbauer spectroscopy

The paper reports on the chemical environment of synthesized iron complexes of Schiff's bases and acetylacetone using Moessbauer spectroscopy.This analytical technique is also used for the preliminary investigation to reveal the change in the chemical state of iron due to exposure to aerated distilled water and atmosphere. The studies evidenced that iron(II) and iron(III) species were formed, and no stereoisomers were found. The exposure to atmosphere converted a part of iron(II) into iron(III) and resulted in distortion of the iron(II) chelates. (author) 9 refs.; 2 figs
