摘要：

Planar heteroaromatic compounds containing amino and nitro functional groups usually have excellent detonation performances. Hereby, the ─NH─ bond bridging two high‑nitrogen fused rings was adopted aiming at constructing a nitrogen‑rich energetic compound with a planar structure. The resulting compound is expected to have a regular packing in crystal and favorable detonation performance and stabilities. Reaction of 2, 6‑diamino‑3, 5‑dinitropyrazine (2) with K2CO3 gives rise to 6‑(2, 6‑diamino‑3, 5‑dinitropyrazine)‑1, 2, 4‑triazole[4, 3‑b][1, 2, 4, 5]tetrazine (3) in a high yield of 81.3%. Compound 3 was characterized by NMR, IR, single crystal X‑ray diffraction. The thermal decomposition process of 3 was studied by differential scanning calorimetry (DSC), and its decomposition temperature (onset) is as high as 254.6 ℃. The detonation performances of 3 (D=7568 m·s-1, P=23.5 GPa) were calculated by Gaussian 09 and Explo5 software. © 2021, Editorial Board of Chinese Journal of Energetic Materials. All right reserved.
