Synthesis and Characterization of Two New Isostructural Iron(III)-Quinates from Aqueous Solutions

Melita Menelaou, A. Salifoglou
Two new iron(III)-quinate complexes were synthesized in aqueous solutions at the optimum pH 3. They were isolated in pure crystalline form and characterized by elemental analysis, spectroscopic techniques (EPR, FT-IR), magnetic studies and X-ray crystallography. The new species contains iron ions in an octahedral environment, where each iron ion coordinates to three quinic acids. The collective physicochemical properties of the derived species project fundamental chemical and structural properties of Fe(III)-hydroxycarboxylate interactions akin to biochemical processes of importance to cellular physiology or aberrant activity.
