Within the framework of the project, quaternary salts of azoles and azines, which are synthetically readily available and technologically feasible, were used as precursors of the organic component A. Heterocyclic cations were obtained by a powerful and well-developed method of electrophilic intramolecular heterocyclisation. Tetravalent selenium and tellurium were used as chalcogen B; bromine and chlorine were used as halogen X. Based on the accumulated array of empirical data on quaternary 1,2,4-triazolium salts (cation A) and TeBr6 anion (BX6), an effective QSPR model was developed based on the relationship between the structural parameters of the studied materials and their properties, which will allow rationalising the search for candidate compounds of target organic-inorganic perovskites A2BX6.
