Purpose: to develop and develop methods of synthesis, to synthesize and identify heterocyclic compounds, to establish their crystal structure, to determine the nature of intermolecular interactions in crystals. Research methods: chemical and physicochemical research methods (elemental analysis, IR, NMR spectroscopy, differential thermal analysis, X-ray diffraction analysis). Methods for the synthesis of new polyfunctional heterocyclic ligands have been developed and developed, and a wide range of nitro, amino, alkyl and carboxy substituted derivatives of 1,2,4-triazole and 4,4-bipyrazole, as well as bis (1,2,4-triazoles) and pyrazolyl substituted 1,2,4-triazoles. New methods for the catalytic reduction of nitropyrazoles have been developed, which have been developed for the synthesis of amino derivatives of 4,4-bipyrazoles. The thermal stability of new organic materials was determined and it was shown that 1,2,4-triazole and 4,4-bipyrazole systems are promising for the synthesis of thermally stable coordination polymers and ionic compounds. The molecular and crystalline structure of new organic compounds and their ionic derivatives was established by X-ray diffraction analysis. Peculiarities of weak intermolecular interactions of different nature in structures of 1,2,4-triazole and 4,4-bipyrazole derivatives (hydrogen bonds, stacking, nonvalent interactions of nitro groups) are revealed, which are important for specific functionalization of crystalline hollow surfaces in coordination polymer structures .  Product Description popup.authors Buvailo Halyna I.
