Description
Summary: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.
