Abstract

In this work, four energetic nitrates, i.e., 4,7-diamino-1H-[1,2,3]triazolo[4,5-d]pyridazin-5-ium nitrate (1), 2,6-diamino-1‑hydroxy-9H-purine-1,7-diium nitrate (2), 6-amino-[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazin-2-ium nitrate (3) and 3,6-diamino-[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazin-2-ium nitrate (4), were prepared and comprehensively characterized. The X-ray diffraction results indicated that compounds 1–4 had different layered structures with the densities in the range of 1.616–1.805 g/cm3. The highest density value of 1.805 g/cm3 was represented in compound 2, which was higher than that of most other nitrates. Moreover, compounds 1–4 had good thermal stabilities, the decomposition temperatures were in the ranged of 165–181 °C, which made them have great potential to further develop. The calculated detonation velocities and detonation pressures of these compounds were in the range of 7678–8925 m/s, and 21.96–32.39 GPa, respectively. The greatest detonation velocity and detonation pressure were observed in compound 3. The specific impulses of these compounds were in the range of 199.8–244.9 m/s. Notably, compound 1 had near infrared laser (λ = 1064 nm) ignition capacity, which was the first example of CHNO based energetic compound with near infrared laser ignition performance.
