Abstract Due to its good stability, density and oxygen balance, the benzofuroxan fused ring framework has attracted particular attention in field of high energy materials. The planar structure facilitates straightforward derivatization with explosophores contributes molecular stability. In this work, a scaffold was utilized develop highly dense energetic material, namely 5,7‐dihydroxy‐4,6‐dinitrobenzo[c][1,2,5]oxadiazole 1‐oxide ( DHDNBF ). successive inclusion like nitro (−NO 2 ) oxidative functionality hydroxyl (−OH) on resulted an impressive (ρ=1.91 g cm −3 positive balance (6.20 %) Furthermore, hydroxy groups enable formation dicationic salts 3 – 7 , contributing additional modifications overall performance. Energetic 4 5 exhibit significantly higher densities ranging from 1.84 1.87 possess favorable approaching zero or equal zero. A marked improvement thermal stabilities observed all compared their neutral counterparts, . (D v =8459 m s −1 P=32.10 GPa) =8539 P=30.37 performance, comparable that well‐known explosives such as LLM‐105 =8560 P=33.4 GPa). Overall, characteristics make them potential candidates for use benzofuroxan‐based secondary primary explosives, respectively, various military civilian applications.

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