those of crystal II. The thermal behavior of the crystal I was studied by differential scanning calorimetry (DSC)–thermal gravimetric (TG) analysis, melting peak is at 94.80 °C, and two decomposition exothermic peaks are at 126.39 °C and 212.10 °C, respectively, in DSC curve. According to the Kissinger and Flynn–Wall–Ozawa methods, the activation energy ( E ) calculated for the first decomposition of the
通过X射线单晶衍射测量了两种不同的1,3,5-三硝基-4,6-二叠氮苯(C 6 HN 9 O 6 )单晶。C 6 HN 9 O 6 的分子量为295.16。晶系I系正交晶系,空间群为Pbca,a = 10.5199 (19) nm, b = 13.436 (3) nm, c = 15.235 (3) nm, β = 90°, V = 2153.4 (7) nm 3 , Z = 8, Dc = 1.821 g cm -3 , μ = 0.164 mm -1 , F (000) = 1184。晶体 II 系统是四方的,空间群是 P42/no a = b = 19.412 (5) nm, c = 5.9603 (17) nm, β = 90°, V = 2246.0 (13) nm 3 , Z = 8, Dc = 1.746 g cm -3 , μ = 0.157 mm -1 , F (000)
