“…The energetic-MOFs are constructed by metal ions and organic ligands, such as azides, furazans, triazoles, and tetrazoles, via coordination bonds, which give one-dimensional (1D), two-dimensional (2D) or three-dimensional (3D) structures 17–20 . Especially noteworthy is the fact that 3D frameworks usually possess more complicated connection modes than 1D and 2D frameworks, which could further enhance their structural stability 21 .…”

The pentazolate anion, as a polynitrogen species, holds great promise as a high-energy density material for explosive or propulsion applications. Designing pentazole complexes that contain minimal non-energetic components is desirable in order to increase the material’s energy density. Here, we report a solvent-free pentazolate complex, AgN5, and a 3D energetic-framework, [Ag(NH3)2]+[Ag3(N5)4]ˉ, constructed from silver and cyclo-N5ˉ. The complexes are stable up to 90 °C and only Ag and N2 are observed as the final decomposition products. Efforts to isolate pure AgN5 were unsuccessful due to partial photolytical and/or thermal-decomposition to AgN3. Convincing evidence for the formation of AgN5 as the original reaction product is presented. The isolation of a cyclo-N5ˉ complex, devoid of stabilizing molecules and ions, such as H2O, H3O+, and NH4+, constitutes a major advance in pentazole chemistry.

“…While this analysis shed light on the composition of 1 , we still felt that we had a less than complete understanding of this material. Therefore, in a separate study, a crystal of 1 was prepared by recrystallization, and the solid state structure was solved using single crystal X-ray diffraction data . The structure is presented in Figure .…”

Copper(I) 5-nitrotetrazolate (DBX-1) has emerged in recent years as a primary explosive that could serve as a replacement for lead azide (LA), a widely used explosive that has fallen out of favor due to its toxicity and chemical compatibility issues. While there is a significant amount of interest in this material, the development of DBX-1 has been hampered by the tedious and poorly understood chemical process for its preparation. To consistently produce DBX-1, two explosive intermediates must be isolated, and one of them requires purification. In this article, we present an improved process for the synthesis of DBX-1. In this process, neither of these intermediates needs to be handled by an operator, and the purification step is no longer necessary. It would be practical to perform the entire process under remote control, a necessity for energetic material manufacturing. We discuss the implications of our findings for the development of a robust process for the reproducible production of high quality DBX-1.

“…The primary explosive has characteristics of starting function and sensitive to stimulus. At present, as the battlefield environment becomes more and more complex, the requirements for primary explosives are becoming more and more stringent [5][6][7]. In addition to the characteristics of high energy output and low limit priming charge, the high temperature resistance has gradually attracted attention [8][9].…”

The research on novel high-temperature resistant primary explosives is an inevitable trend to adapt to the development of weapons. In this paper, high temperature resistant primary explosive cadmium azide was prepared from sodium azide and cadmium nitrate tetrahydrate by hydrothermal reaction. Then, the high-temperature storage performance was tested by cook-off test, and the influence of high temperature was analyzed in combination with microscopic morphology, crystal structure, and thermal decomposition temperature. The reliable ignition voltage was tested by electric ignition sensitivity, and the initiation performance of cadmium azide was verified by using CL-20 as secondary explosive. The results show that cadmium azide is an excellent high temperature resistant initiating agent primary explosive with the thermal decomposition temperature of 384.21°C and a 50% electric ignition voltage of 4.82 V, which can reliably initiate the CL-20 into complete detonation.
