Structural and Chemical Research of Coordination Compounds of Hexaaqua Bisbenzol-1, 2, 4, 5- Tetracarbonate Diiron (II) With A Layered-Porous Structure, For Heavy Crude Oil

The complex compounds of diiron (II) bisbenzoll, 2, 4, 5 tetracarbonate were synthesized for the first time with porous structure. This article presents the results of X-ray diffraction, elemental and IR analyzes of spectroscopic derivatographic complex compound of 1,2,4,5-bis benzene tetracarbonate of diiron (II). By means of the indicated physical-chemical analyzes the individual coordination form of carboxyl groups, chemical formula and unit cell parameters of the complex compound have been identified. Also the process of thermal degradation of the studied complex has been studied. It was revealed that the compound after losing six molecules of water is resistant until the temperature 300°С. In all likelihood coordinately related the water molecules form intermolecular hydrogen bonds both with oxygen of the carboxyl groups, and among themselves. In all likelihood coordinately related the water molecules form intermolecular hydrogen bonds both with oxygen of the carboxyl groups, and among themselves. Here molecules of coordination water in the different layers play an active role in this interaction. Thus, a two-dimensional structure of a complex compound by means of the hydrogen bonds is transformed into 3D structure.
