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