High-dimensional energetic coordination compounds (ECCs) exhibit high stability and low sensitivity owing to their complex network structure, making them valuable in functional materials such as combustion catalysis insensitive detonating explosives. Four ECCs, [Co(DNBT)(H2O)4]n (ECC-1), [Ni(DNBT)(H2O)4] (ECC-2), [Cu2(DNBT)2(H2O)3MeOH] (ECC-3), [Zn(DNBT)(H2O)4] (ECC-4), were synthesized by modifying the metal centers using 5,5'-dinitro-4H,4'H-3,3'-bi(1,2,4-triazole) (DNBT) ligands. After changing solution environment adding auxiliary ligand 4H-1,2,4-triazol-4-amine (4-ATr), we obtained three ECCs with similar structures once again: [Co2(DNBT)2(4-ATr)3(H2O)2] (ECC-5), [Ni2(DNBT)2(4-ATr)3(H2O)2] (ECC-6), [Cu2(DNBT)2(4-ATr)3] (ECC-7). fewer water molecules chosen for laser ignition detonation tests evaluate laser-induced capabilities, indicating potential applications initiators. The response behavior differs between [Cu2(DNBT)2(4-ATr)3]. exhibits excellent response, a minimum initiation energy of 11 mJ short lengthy delay 2.31 ms, whereas is less sensitive under same conditions. Theoretical calculations at different power densities indicate that possesses more efficient photothermal conversion. This reduced may stem from presence water. charge transfer these thoroughly analyzed through theoretical structural studies.

This study effectively synthesized thiazole-4-carbohydrazide (SZCA) and its ionic salt SZCA·HClO4 energetic complex Cu(SZCA)2(ClO4)2 (ECC-1). The new compound SZCA, ECC-1 were fully characterized through elemental analysis, infrared spectroscopy, 13C NMR spectroscopy thermal stability analysis. combustion heat of was measured by oxygen bomb calorimetry, detonation performance predicted Kamlet-Jacobs formula EXPLO5, respectively. mechanical sensitivity tested using BAM method. In particular, we comprehensively evaluated the initiation ability lead plate destruction experiment laser experiment. results show that have a decomposition temperature 236 °C, exhibits acceptable (impact sensitivity: 3.4 J, friction 4 N), decent properties (D: 6.6 km s−1, P: 21.3 GPa). And could be initiated single-pulse (λ: 808 nm, 20 W, t: 3 ms), successfully detonated next charge, such as RDX CL-20.

Revamping the structure of energy storage is an efficient strategy for striking a balance between performance and sensitivity energetic materials to achieve high reduced sensitivity. In continuation prior research, this study utilized ligand 3,5-dimethyl-1H-pyrazole-4-carbonhydrazide (DMPZCA) innovatively designed synthesized compound ECCs [Cu(HDMPZCA)2(ClO4)2](ClO4)2·2H2O (ECCs-1·2H2O). Compared with former solvent-free ECCs-1 refers innovative material characterized by dual involving ionic salts coordination compounds. Due these unique structures, exhibits increased [ClO4-] content, higher oxygen constant (OB = -7.9%), improved mechanical (IS 8 J, FS 32 N). Theoretical calculations support superior detonation ECCs-1. Additionally, experimental results confirm its ignition capability through lower-threshold lasers highlight outstanding initiation potential explosive power, making it suitable candidate primary explosives.

Abstract Mn 2 (C H 6 N ) 4 (NO 3 ·2H O ( as one of the energetic coordination complexes was chosen for high‐pressure research. In this work, analyzed by in situ Raman scattering, infrared absorption, and synchrotron angle‐dispersive X‐ray diffraction (ADXRD) technologies up to ~20 GPa at room temperature. The vibrational modes ambient pressure were comprehensively resolved based on experimental results. Detailed spectral analyses revealed that underwent three pressure‐induced phase transitions 0.5, 2.5, 5.7 GPa, respectively. ADXRD experiments confirmed existence these spectra analyses. Based analysis changes lattice parameters under pressure, it can be considered deformation 3‐hydrazino‐4‐amino‐1, 2, 4‐triazole (HATr) ligand led first transition, distortion triazole ring induced second rearrangement hydrogen bonds resulted third transition. addition, inferred from data may have experienced abnormal expansion during This work lay foundation further investigating structure properties pressure.
