本文报道了6-硝氨基-7-硝基-8-氨基四唑并[1，5-B]哒嗪（1）及其碱金属盐（2-6）的合成和性质。在特定条件下，6-硝氨基和8-氨基发生水解，生成一系列碱金属盐6-硝氨基-7-硝基-8-羟基四唑并[1，5-B]哒嗪（7，12）和6-氨基-7-硝基-8-羟基四唑并[1，5-B]哒嗪（8-11）。通过SXRD、IR、EA、HRMS和NMR等手段对它们的结构进行了表征。用差热分析（DTA）和热重分析（TGA）研究了其热稳定性。在ΔfHandρ的基础上，利用EXPLO 5软件计算了炸药的爆轰性能（vDandp）。还测量了机械灵敏度（IS，FS）。结果表明，化合物1 - 12具有良好的热稳定性（Td > 175 °C）、高能级（vD > 6700 m s-1）和低灵敏度（IS ≥ 18 J），是一种有前途的含能材料。
In this study, the synthesis and properties of 6-nitramino-7-nitro-8-aminotetrazolo[1,5-b]pyridazine (1) and its alkali metal salts (2–6) were presented. The hydrolysis of 6-nitramino and 8-amino from1was occurred at the specified conditions, which generated a series of alkali metal salts of 6-nitramino-7-nitro-8-hydroxy-tetrazolo[1,5-b]pyridazine (7, 12) and 6-amino-7-nitro-8-hydroxy-tetrazolo [1,5-b]pyridazine (8-11). Their structures were characterized by SXRD, IR, EA, HRMS and NMR, respectively. The thermal stability was investigated by using DTA and TGA techniques. On the basis ofΔfHandρ, the detonation performances (vDandp) were calculated using EXPLO5 software. The mechanical sensitivities (IS, FS) were also measured. The results show that compounds1–12display good thermal stability (Td> 175 °C), high energy level (vD> 6700 m s−1) and low sensitivities (IS ≥ 18 J) as promising energetic materials.
