Abstract

In order to further explore the effect of ligands on the performance of primary explosives and gain a deeper understanding of the coordination mechanism, we designed furan-2-carbohydrazide (FRCA), a ligand, by using oxygen-containing heterocycles and carbohydrazide. Then, FRCA and Cu(ClO₄)₂ were used to synthesize coordination compounds [Cu(FRCA)₂(H₂O)(ClO₄)₂]·CH₃OH (ECCs-1·CH₃OH) and Cu(FRCA)₂(H₂O)(ClO₄)₂ (ECCs-1). The structure of the ECCs-1 was confirmed by single-crystal X-ray diffraction, IR and EA characterization. Further experiments on ECCs-1 show that ECCs-1 has good thermal stability, but is sensitive to mechanical stimuli (impact sensitivity = IS = 8 J, friction sensitivity = FS = 20 N). The predicted value of the detonation parameter is D_{EXPLO 5} = 6.6 km s^-1, P_{EXPLO 5} = 18.8 GPa, but the ignition test, laser test, and lead plate detonation experiment show that ECCs-1 has excellent detonation performance, which is very worthy of attention.
