“…Based on this, we have prepared a series of carbohydrazide-based energetic coordination compounds. [16][17][18][19] However, the carbohydrazide group has a downside, which is its high reactivity due to multiple reaction sites. When two carbohydrazide groups are in ''adjacent'' positions of the skeleton ring, they are prone to undergo a cyclization reaction to form diazine rings in acidic environments.…”

“…The difference is that the ligands here are diverse. First, the nitrogen heterocyclic ring itself may have coordination sites, especially the tetrazole ring. − Second, groups with strong coordination ability, such as −NH 2 , −NHNH 2 , and −CONHNH 2 , are added to the nitrogen heterocyclic ring through substitution reaction so as to form metal coordination bonds with central ions. Ag + , Cu 2+ , Ni 2+ , Co 2+ , Cd 2+ , Pb 2+ , and Mn 2+ are commonly used as central metal ions. − …”

In addition to the three classical methods for adjusting the performance of energetic complexes, in order to explore the influence of different bonding types on the performance of energetic materials, we designed ionic salts PZCA•HClO 4 (3) and ECPs [Ag(PZCA)ClO 4 ] n (4) with PZCA(1H-pyrazole-4carbohydrazide) as the ligand. They use the same ligands and oxidizing acids and also have the same N/O number. On the basis of their structures and compositions confirmed by infrared spectroscopy, elemental analysis, and single-crystal X-ray diffraction, the characterization of physical and chemical properties shows that 4 has better thermal decomposition behavior (ΔT = 30 °C), more suitable mechanical sensitivity (IS = 5 J, FS = 9 N), and more outstanding initiation performance. After studying the decomposition mechanism, we find that different types of bonds (H bond or coordination covalent bond) lead to different decomposition mechanisms (redox reaction or free radical reaction) and, finally, show great differences in explosive properties.

“…For example, the introduction of bis-1,2,4-triazoles and bis-1,2,4-oxadiazole bridges can reduce the sensitivity of EMs and increase their thermal stability. , Therefore, “nitrogen-rich materials” have good advantages in balancing the contradiction between energy and sensitivity of energetic materials. , As for the primary explosives of the ECCs type, can “nitrogen-rich materials” also play a role? In our previous work, we designed a variety of ligands and their ECCs with heterocycles as the modifier and hydrazide as the coordination group, such as Cu(TZCA) 2 (ClO 4 ) 2 , Cu(AOCA) 2 (ClO 4 ) 2 , and Cu(PZCA) 2 (ClO 4 ) 2 . Although these ECCs have good detonation properties, they still have high mechanical sensitivity.…”

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·C 2 H 5 OH) and [Cu(PRCA)2(H2O)(ClO4)]ClO4·2H2O (ECCs-1·2H 2 O) 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 (T d = 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 (D EXPLO 5 = 6.2 km s–1, P EXPLO 5 = 16.2 GPa). However, detonation performance tests show that ECCs-1 has an extremely strong detonation ability.
