A safe synthesis method for a new generation of primary explosives based on the guiding ideology of the coordination chemistry strategy with excellent performance capabilities has been developed. Based on 3-amino-1-nitroguanidine (ANQ), metal cations Co(II), Ni(II), and high-energy azide groups (N₃^–), we created two coordination polymer primary explosives which are solvent-free and chlorine-free, and further confirmed by IR, elemental analysis, and single crystal X-ray diffraction. Thermal stability experiments have shown that their thermal decomposition temperature all exceed 170 °C. Sensitivity test and explosion parameter simulation show that 2 and 3 have excellent detonation performance and safety performance. In addition, the results of the initiating efficiency test support that 2 can be used as a suitable primary explosive.

叠氮基的竞争配位：基于 3-氨基-1-硝基胍的无溶剂无氯初级炸药的合成

以配位化学战略为指导思想，开发出一种性能优良的新一代起爆药的安全合成方法。基于 3-氨基-1-硝基胍 (ANQ)、金属阳离子 Co(II)、Ni(II) 和高能叠氮化物基团 (N ₃^– )，我们创造了两种无溶剂和不含氯，并通过红外、元素分析和单晶 X 射线衍射进一步证实。热稳定性实验表明它们的热分解温度均超过170℃。敏感性试验和爆炸参数模拟表明，2和3具有优良的爆震性能和安全性能。此外，起爆效率测试结果支持2可作为合适的起爆药。
