4-oxadiazol-2-yl)furazan monohydrate (2·H2O), which is a combination of the nitroaminofurazan and 1,3,4-oxadiazole rings, was obtained by the nitration of 3-amino-4-(5-amino-1,3,4-oxadiazol-2-yl)furazan (1) with 100% nitric acid. Several energetic derivatives of 2 were prepared and fully characterized by multinuclear NMR, and IR spectroscopy, as well as elemental analysis. X-ray analyses for 1, 2·H2O and
Abstract Two new ionic complexes, (DATr)2[Li2(TNR)2·2H2O]·2H2O (1) and (DATr)[Zn(DATr)Cl3] (2), were synthesized by using 3,4-diamino-1,2,4-triazole (DATr) as outer cation. X-ray single-crystal diffraction analysis revealed that the two complexes crystallize in triclinic and orthorhombic crystal systems, respectively. Differential scanning calorimetry was applied to assess the thermal decomposition
4-triazolium chloride aqueous solution with styphnic acid methanol solution under the reaction medium of aqueous ammonia. The title double salt was characterized by elemental analysis (EA), Fourier transformation infrared spectrum (FT-IR), and X-ray single-crystal diffraction. It crystallizes in the monoclinic crystal system with space group P21/n. Its density is 1.780 g·cm–3. Compound 2 is thermal
Abstract Nitrogen-rich energeticsalts and cocrystal have attracted considerable attention in recent years. To assess the formation of cocrystal or salt, acid dissociation constant (pKa) values of the isomeric co-formers were calculated in this work and significant differences were observed. Twosalts and one cocrystal based on H2BT (1H, 1’H-5,5’-bitetrazole), DATr (4,5-diamino-4H-1,2,4-triazole),
