Objective: to investigate the behavior of 4,4-bipyrazole and its derivatives in alkaline solutions, to develop methods of synthesis and to obtain ionic pyrazolates; determine the crystal structure of ionic compounds and framework coordination polymers based on oxo (fluoro) metals, 1,2,4-triazole and pyrazole ligands; to establish the nature of intermolecular interactions in crystals. Research methods: chemical and physico-chemical research methods (elemental analysis, IR, NMR spectroscopy, X-ray diffraction analysis, thermal analysis). Crystallographic parameters and features of crystal structure of 73 new ionic pyrazolate compounds and framework coordination polymers based on heterocyclic ligands - pyrazole and 1,2,4-triazole derivatives, oxofluoride building blocks and oxo (fluoro) metals (VV, NbI) , WVI). New features of -coordination of heterocyclic ligands have been revealed, in particular, the selectivity of -coordination in heterometallic systems and the order of affinity of alkali metal cations to -ligands. The topology of coordination frameworks, methods of coordination of organic and inorganic co-ligands, characteristics of intermolecular interactions are determined. The presence of crystalline microcavities was determined, the free volume was calculated, the thermal stability was investigated and the temperature regime of desolvation with the formation of microporous materials was determined.  Product Description popup.authors Buvailo Halyna I.
