Synthesis and Physico-Chemical Studies of Complex Compounds of Iron (II) and (III) With Phthalic Acid

The coordination compounds of iron (II) and (III) with phthalic acid were synthesized. The compounds were studied by X-ray diffraction (XRD), differential thermal (DTA), and IR spectroscopy. It has been established that, regardless of the oxidative number of iron, the synthesis products have the same chemical composition and chemical formula - [Fe2(o-C6H4(COO)2)3]. It also found that the carboxyl groups of phthalate dianion have a monodentate and bridging function, and the complex itself is a polymer-layered structure. Based on the obtained results, given the proposed schematic structure of the complex compound. Also were studied the thermal stability of the complex compound in the temperature range 20-660°С and the supramolecular interaction of this substance with the rheological properties of heavy commercial oils.
