Synthesis and Characterization of Metal-Organic Polymer based on Fe(III)

Abstract

In this work, a coordination polymer based on iron trinuclear acetate was synthesized. The coordination polymer was obtained in two stages. At the first stage [Fe3O(CH3CO2)6(H2O)3]·2H2O – tricyclic iron acetate was synthesized. As the dicarboxylate ligand, we chose muconic acid, which is not toxic to the body. Double bonds in its structure create additional nodes for interaction with drugs. The optimal conditions for the synthesis of a coordination polymer based on tricyclic iron acetate and muconic acid were selected: solvothermal synthesis at 78 °C, autogenous pressure and using ethanol as a solvent. The resulting coordination polymer is a nanosized mesoporous framework with a narrow pore distribution, an average radius of~1.18 nm, and a developed specific surface area of 512.1 m2/g. The composition and crystal structure of tricyclic iron acetate and a coordination polymer based on it have been confirmed by the methods of elemental and X-ray phase analysis.
