superior thermal stability (110.5–116.4 °C) than most other reported nonmetallic pentazole salts (Tonset: 80–110 °C), and compound 8 has the highest crystal density (1.722 g·cm–3/173 K) of nonmetallic pentazole salts to date. All salts have been thoroughly characterized by NMR (1H and 13C) spectroscopy, infrared (IR), Roman (RA), and elemental analysis. The decomposition temperature of all salts displays more
在这项工作中,三种新的非金属五唑盐(6 - 8)的基础上或呋咱-4-硝基吡唑合成。将一些共面基团引入化合物中以改善晶体堆积的平面度。4-氨基1,2,5-恶二唑-3-碳酰肼酰胺五唑酸酯(6),5-(4-氨基1,2,5-恶二唑-3-基)-4 H -1,2,4-三唑-3,4-二胺五唑酸酯(7)和5,5'-(4-硝基-1 H-吡唑-3,5-二基)-双(4 H -1,2,4-三唑-3,4 -二胺)戊唑酸酯(8)均表现出比大多数其他报告的非金属戊唑盐(T发作)更稳定的π-π堆积和优异的热稳定性(110.5-116.4°C)。:80–110°C),并且化合物8具有迄今为止非金属戊唑盐的最高晶体密度(1.722 g·cm –3 / 173 K)。所有盐均已通过NMR(1 H和13 C)光谱,红外(IR),罗马(RA)和元素分析进行了全面表征。所有盐的分解温度均显示超过110°C,这是通过差示扫描量热法(D
