Synthesis and crystal strucrure of Bis-(2,6-diaminopyridine) tetrachlorid zinc(II)

In the presented work, the synthesis of a complex resulting from the reaction of 2,6-diaminopyridine with the Zn(II) ion in an alcohol solution of hydrochloric acid is described for the first time. The composition, molecular and crystal structure of the synthesized complex were determined by X-ray structural analysis. The structure of the new complex, its crystallographic data, and the geometry of hydrogen bonds in the crystal system were determined. The composition of the metal complex was confirmed by elemental analysis, and the existing chemical bonds were studied by IR spectroscopy. The surface of the crystals was studied according to Hirschfeld. To determine the stability of the obtained complex, its thermal analysis was carried out. The stability of the complex, caused by intramolecular hydrogen bonds, was confirmed.
