Single-compound heat-resistant explosives are an important class of high-energy compounds with excellent thermal stability. In this paper, a novel thermally stable explosive 3,5-dinitro-N²,N⁶-bis(2,4,6-trinitrophenyl)pyrazine-2,6-diamine (ZXC-71) is reported. The commercially available 2,6-dichloropyrazine was used as raw materials to prepare this compound with a straightforward method. The crystalline structure of ZXC-71 was determined by single-crystal X-ray diffraction. From the calculated standard molar enthalpy of formation and the measured density, the Chapman–Jouguet detonation properties were predicted. The detonation velocity (D), detonation pressure (P), and density (ρ) of ZXC-71 are 8608 m s⁻¹, 29.8 GPa, and 1.86 g cm⁻³, respectively. ZXC-71 also exhibits remarkable impact sensitivity (FS=22 J).

3,5-二硝基-N2,N6-双(2,4,6-三硝基苯基)吡嗪-2,6-二胺(ZXC-71)：具有优异性能的热稳定炸药

单一化合物耐热炸药是一类重要的高能化合物，具有优良的热稳定性。本文报道了一种新型热稳定炸药3,5-二硝基-N ² ,N ⁶ -双(2,4,6-三硝基苯基)吡嗪-2,6-二胺( ZXC-71 )。以市售的2,6-二氯吡嗪为原料，通过简单的方法制备了该化合物。通过单晶X射线衍射测定了ZXC-71的晶体结构。根据计算的标准摩尔形成焓和测量的密度，预测了查普曼-茹格爆轰特性。ZXC-71的爆速( D )、爆压( P )、密度( ρ )分别为8608m s ^-1、29.8GPa、1.86g cm ^-3。ZXC-71还表现出显着的冲击敏感性（FS = 22 J）。
