Article Synopsis
- The structure of energetic compounds significantly influences their performance, with even slight variations impacting their effectiveness in different application scenarios.
- Researchers synthesized two silver(I)-based complexes, ECPs-1 and ECPs-2, using isomeric ligands, and confirmed their structures through various analytical methods.
- Although both complexes have good thermal stability, ECPs-2 shows lower thermal decomposition temperature and mechanical sensitivity while demonstrating stronger explosive power, making it a potential candidate for applications such as laser initiation.
In order to preserve the coordinating ability of the hydrazide group, we used retrosynthetic analysis to design and synthesize ligand furan-2,5-dicarbohydrazide and its complex [Cu(FDCA)(HO)ClO](ClO)·HO (). The structure of the product was confirmed by single-crystal X-ray diffraction, infrared spectroscopy, and elemental analysis. The solvent-free target material exhibited good thermal stability, sensitivity to mechanical stimuli, and excellent explosive properties.

Then, FRCA and Cu(ClO) were used to synthesize coordination compounds [Cu(FRCA)(HO)(ClO)]·CHOH () and Cu(FRCA)(HO)(ClO) (). The structure of the was confirmed by single-crystal X-ray diffraction, IR and EA characterization.

First, tannic acid polymerized in situ on the surface of CL-20 crystals. Then, [Cu(ANQ)(NO)] and [Ni(CHZ)](ClO) were hydrothermally formed on the surface of CL-20/TA, respectively.
