摘　　要：利用水热法制备了一个单核含能配合物[Ni(DABT)(H_(2)O)_(4)]SO_(4)·H_(2)O(1)(DABT=3,3’-二氨基-5,5’-二(1H-1,2,4-三唑))和一个含能离子盐DABT·SO_(4)(2)。结构分析表明,1和2均通过三唑环的π-π堆积作用及其氢键相互作用形成了三维超分子结构。研究了1和2的红外光谱,紫外可见光谱;运用TG-DSC热分析仪研究了1的热分解行为,结果表明1在失去水分子后可以稳定到350℃才放热分解;探究了2对推进剂主要组分的热分解行为,结果表明2对AP具有一定的燃烧催化作用。A single nuclear energetic complex[Ni(DABT)(H_(2)O)_(4)]SO_(4)·H_(2)O(DABT=3,3'-Diamino-5,5'-bis(1H-1,2,4-tria-zole))and an energetic ionic salt DABT·SO_(4)(2)were prepared by the hydrothermal method.Structural analysis revealed that both 1 and 2 form three-dimensional supramolecular structures through-t stacking of the triazole ring and hydrogen bond interactions between the sulfate ion and other groups.The infrared spectrums and UV spectrums of 1 and 2 were studied;the thermal stability of 1 was studied using thermogravimetric-differential scanning calorimetry(TG-DSC),and the results show that if lost water molecules 1 can be stabilized until 350 C;the effect of 2 for the thermal decomposition of the main propellant components was explored,and the results show that 2 has certain combustion catalytic effect on AP.
