“…On the one hand, the EXPLO5 program did not support the element of Rb temporarily, and on the other hand, calculational deviations existed between different programs, therefore only EXPLO5 program was used in this study, and the detonation performances of NANTT-7 were not calculated. Different from the NANTT energetic salts and the NANTT co-crystal, composed of NANTT with energetic ligands, the metal atoms of the ECPs could not directly release huge amounts of energy, but they can represent as the framework (generating the bonds between the metal atoms and the energetic material molecules) to decrease their sensitivity and increase their decomposition temperatures. − …”

A series of novel energetic materials (EMs) based on a single triazole−tetrazole material, (Z)-N-(5-nitro-2-(1Htetrazol-5-yl)-2,4-dihydro-3H-1,2,4-triazol-3-ylidene)nitramide (HNANTT) with tremendous physicochemical (d = 1.833 g cm −3 and ΔH f = 715.8 kJ mol −1 ) and energetic properties (D v = 9209 m s −1 and P = 36.38 GPa), were obtained. Detailed crystal structures of HNANTT and NANTT-5, 7, 8, 9, 11, and 13 were determined by single-crystal X-ray diffraction. Based on HNANTT, three kinds of energetic coordination polymers (ECPs) (NANTT-5, 7, and 8), four energetic salts (NANTT-9, 10, 11, and 12), and one energetic cocrystal (NANTT-13) were prepared and characterized to develop EMs with different kinds of advantages. By modifying HNANTT, all NANTT derivatives (except NANTT-10) showed good mechanical sensitivity (IS > 40 J, FS > 360 N), with NANTT-ECP-8 achieving the highest density (2.729 g cm −3 ) and thermal stability (287 °C), NANTT-12 has the highest detonation performances (D v = 9225 m s −1 and P = 30.87 GPa) among NANTT materials, while the NANTT co-crystal of 13 exhibited the best comprehensive performance, with superior detonation properties (D v = 9035 m s −1 and P = 30.12 GPa), higher thermal stability (236 °C), and N + O content of 83.2%.

“…Among the most essential properties of energetic materials is the sensitivity to mechanical stimuli; thus, the lower impact sensitivity limit of 7 was 120 mm at a drop weight of 10 kg, while the lower friction sensitivity limit was 5500 kgf/cm 2 (539.36 MPa), which is almost two times less sensitive than compound 5 [ 17 ].…”

“…We have previously reported the synthesis of tris(carbohydrazide-N,O)nickel(II)dinitramide by reacting the nickel salt of dinitramic acid with carbohydrazide (CHZ) [ 17 ]. This synthesized complex is a nitrogen-rich compound (46%) that is well-soluble in water and insoluble in alcohol, explodes when heated above 180 °С, is very sensitive to impact (the lower limit < 50 mm) and friction (the lower limit = 2200 kgf/cm 2 ), and, therefore, is dangerous to work with.…”

Dinitramic acid salts are promising components as oxidizers and burning-rate modifiers of high-energy compositions. However, most of these salts are not free of drawbacks such as hygroscopicity. Therefore, their application under special conditions of use and storage is limited. The synthesis and storage of stable dinitramic acid salts is a topical issue. Here, we synthesized an adduct starting from the nickel salt of dinitramic acid with carbohydrazide and glyoxal to settle the problem of stability and storage of that salt. The chemical composition of the adduct was confirmed by infrared spectroscopy and elemental analysis. The Ni content was determined by atomic emission spectroscopy. Thermogravimetric DSC and TGA analyses showed the adduct to have three decomposition stages. The adduct exhibits a good thermal stability and a low sensitivity to mechanical stimuli. Here, the adduct is demonstrated to be a promising burning-rate inhibitor of pyrotechnic compositions.

“…We previously reported the synthesis of new dinitramide salts, starting with carbohydrazide and a heterocyclic macrocycle (1), which inhibited properties with respect to the pyrotechnic composition burning rate [21][22][23] (Figure 1). In continuation of the research in this direction, we here propose investigating a structural analogue of compound 1 as the cation for the synthesis of new dinitramide salts.…”

A simple, one-pot regioselective method for the synthesis of a high-nitrogen tricycle, 2,3,4а,6,7,8а,9,10-octaaza-4,8-dioxo-3,4,4a,7,8,8а,9,9a,10,10а-decahydroanthracene, with a yield of 27% was developed on a starting urea basis as a result of studies focused on finding new, more efficient approaches to the synthesis of high-energy derivatives of dinitramic acid (DNA). This tricycle was further treated to furnish 2,3,4а,6,7,8а,9,10-octaaza-4,8-dioxo-3,4,4a,7,8,8а,9a,10а-octohydroanthracene-9,10-ion-bis(dinitramide). The resultant salt of dinitramic acid exhibited inhibitory properties towards the burning rate of pyrotechnic compositions, reducing it by 30%, and possessed good thermal stability due to a high decomposition temperature above 260 °C and a low sensitivity to mechanical stimuli. The structural features of the new tricycle-based dinitramide salt were characterized via 2D NMR spectroscopy and double-focusing sector mass spectrometry (DFS).
