SYNTHESIS AND STRUCTURAL CHARACTERIZATION OF MN(II) ACETATE COMPLEXES WITH 3-AMINO-1,2,4-TRIAZOLE: AN IR SPECTROSCOPIC STUDY

A complex combination of Mn(II) acetate with 3-amino-1,2,4-triazole with polymer structure [C3.556H6.222Mn0.444N3.556O1.778] was synthesized. The composition and structure of the synthesized complex were determined using modern physicochemical methods (IR spectroscopy, elemental analysis, thermal analysis, X-ray diffraction analysis, and Hirschfeld surface analysis). Based on derivative analysis, the causes of endo- and exo-effects were determined, and the thermal products were identified. X-ray diffraction analysis showed that in the formation reactions of the 3-amino-1,2,4-triazole complex, the central atom of the triazole forms a polymer structure through monodentate coordination through nitrogen atoms. ring, and the oxygen atom of the acidic ligand with manganese. According to Hirshfeld surface analysis, the most important effects on the crystal structure correspond to the pair of atoms H•••H (51.8%) and H•••O/O•••H (20.6%). interaction between the hydrogens of the methylene and benzene rings
