N2 - In order to study the design and preparation of new coordination primary explosive, the influence of ligand on the performance was explored. Using the low-energy, low-nitrogen pyrrole as the skeleton and the hydrazide group as the target, the ligand 1H-pyrrole-2-carbohydrazide (PRCA) was designed, the two ECCs [Cu(PRCA)2(H2O)(ClO4)]ClO4·C2H5OH (ECCs-1·C2H5OH) and [Cu(PRCA)2(H2O)(ClO4)]ClO4·2H2O (ECCs-1·2H2O) were prepared, and [Cu(PRCA)2(H2O)(ClO4)]ClO4 (ECCs-1) was obtained by a simple drying method. The structure of the target compound was confirmed by single-crystal X-ray diffraction, infrared (IR), and elemental analysis (EA) characterization. Physicochemical performance tests show that ECCs-1 has better thermal stability (Td = 219 °C) and is more sensitive to impact sensitivity (IS = 7 J) and friction sensitivity (FS = 16 N). The detonation performance prediction results show that the detonation velocity and pressure of ECCs-1 are not high (DEXPLO 5 = 6.2 km s-1, PEXPLO 5 = 16.2 GPa). However, detonation performance tests show that ECCs-1 has an extremely strong detonation ability.
