1,5-Diaminotetrazole (DAT) is a fascinating component in the construction of high-energy-density materials because of its extremely high nitrogen content (∼84%). Three DAT nitro-substituted azolate salts were synthesized and fully characterized by IR, NMR, elemental analysis, thermal stability, phase behavior, and density. 1,5-Diamino-4H-tetrazolium 5-nitrotetrazolate salt (2) crystallizes in the orthorhombic system Pbca. The detonation pressure (P) values calculated for these salts range from 28.05 to 29.88 GPa, and the detonation velocities (D) from 8343 to 8655 m s−1, which make them competitive energetic materials. Each of the compounds has an oxygen balance approaching zero (−23.8 to −33.5%). Their impact sensitivities were determined. The salts were compared using natural bond orbital (NBO) analysis of the nitro-substituted azolate anions. These CHNO-explosives, DAT nitro-substituted azolate salts, are potential green energetic materials which are obtained via a straightforward synthetic route.
1,5-二氨基四氮唑(DAT)因其极高的氮含量(∼84%)而成为制造高能量密度材料的重要成分。我们合成了三种硝基取代的氮杂环酸盐,并通过红外光谱、核磁共振、元素分析、热稳定性、相行为和密度对其进行了全面表征。1,5-Diamino-4H-tetrazolium 5-nitrotetrazolate 盐(2)以 Pbca 正方晶系结晶。计算得出的这些盐的爆轰压(P)值在 28.05 至 29.88 GPa 之间,爆轰速度(D)在 8343 至 8655 m s-1 之间,这使它们成为具有竞争力的高能材料。每种化合物的氧平衡都接近零(-23.8% 至 -33.5%)。测定了它们的冲击敏感性。通过对硝基取代的氮杂环酸阴离子进行天然键轨道 (NBO) 分析,对这些盐进行了比较。这些 CHNO-爆炸物(DAT 硝基取代的叠氮酸盐)是潜在的绿色高能材料,可通过简单的合成路线获得。
