3,6,7-Triamino-7 H -s-triazolo[5,1-c]-s-triazole was synthesized from triaminoguanidine hydrochloride and cyanogen bromide, and has been prepared at the 30-g scale. A single crystal of 3,6,7-triamino-7 H -s-triazolo[5,1-c]-s-triazole was cultivated, and its crystalline density at 293 K was 1.726 g cm−3. Its heat of formation (Δ H f,solid = 470.5 kJ mol−1) was computed by using the density functional

氨基-7 H -s-三唑并[5,1-c] -s-三唑的单晶,在293 K下的晶体密度为1.726 g cm -3。使用密度泛函理论(DFT)方法计算其形成热( ΔH f,solid = 470.5 kJ mol -1),并通过EXPLO5代码进一步预测其爆炸压力和爆炸速度( D = 9483 m s -1, P = 30.4 GPa)。通过Hirshfeld表面分析研究了标题化合物的分子间相互作用。此外,根据差示扫描量热仪(
DSC)的结果,通过非等温动力学方法评估了其热力学性能,结果表明,基辛格(Kissinger),小泽(Ozawa)和斯塔林克(Starink)方法获得的表观活化能( E a)为223.55、221.61和22。分别为223.73kJ
