Synthesis, structural and spectroscopic features, and investigation of bioactive nature of a novel organic-inorganic hybrid material 1H-1,2,4-triazole-4-ium trioxonitrate

Abstract : The novel inorganic-organic hybrid material 1H-1,2,4-triazole-4-ium trioxonitrate (TAN) have been elaborated and crystallized to the monoclinic system with space group P21/c and the lattice parameters obtained are a = 8.8517(15) Å, b = 8.3791(15) Å, c = 7.1060(11) Å, β = 103.776(7)°, V = 511.89(15) Å3 and Z = 4. In order to enhance (TAN) on the applied plan, biophysicochemical characterization of the title compound have been obtained with experimentally and theoretically. The crystal structure exposed substantial hydrogen bonding stuck between the protonated 1,2,4-triazole ring and the nitrate forming thus sheets parallel to the plans (−1 0 1). The three-dimensional supramolecular network is formed through the π … π interactions involving heterocyclic rings in these sheets. Assessment of intermolecular contacts in the crystal arrangement was quantified by Hirshfeld surface analysis and interactions were analyzed by orbital NBO and topological AIM approaches. This compound was also investigated by means of infrared spectroscopy, electrical conductivity, thermal analysis TG-DTA, and DSC. Moreover, the antioxidant properties of TAN were determined via the DPPH radical scavenging, the ABTS radical scavenging, hydroxyl radical scavenging, and ferric reducing power (FRP). Obtained results confirm the functionality of antioxidant potency of TAN. The molecular structure and vibrational spectral analysis of TAN have been reported by using density functional theory calculations at B3LYP/6-311++G(d,p) level of theory. Molecular docking behaviors of TAN along with well-known triazole antifungal agents (fluconazole, itraconazole, posaconazole, and voriconazole) with saccharomyces cerevisiae CYP51 (Lanosterol 14-alpha demethylase) were investigated. The potent of TAN as an inhibitor was discussed on the basis of noncovalent interaction profile. Furthermore, protonic conduction of this compound has been intentional in the temperature range of 295–373 K.
