用微波法合成了两个新的含能配合物Co（TO）2（DMBA）2（H2O）2（1）和Cu（TZA）（DMBA）（2）（TO = 1，2，4-三唑-5-酮，HTZA =四唑-1-乙酸，HDNBA = 3，5-二硝基苯甲酸）。单晶X-射线衍射结果表明，化合物1具有单核单元的三维超分子结构，化合物2具有一维链的二维超分子结构。热分析表明，配合物1和配合物2的热稳定性分别达到238 °C和270 °C。用Kissinger和Ozawa方法研究了配合物的非等温放热动力学。计算的爆轰性能和感度试验表明，这两种配合物都可以作为潜在的炸药。此外，利用差示扫描量热法研究了这两种配合物作为助燃剂对RDX（1，3，5-三硝基-1，3，5-三嗪烷）热分解的促进作用。
Two new energetic complexes, Co(TO)2(DNBA)2(H2O)2 (1) and Cu(TZA)(DNBA) (2) (TO = 1,2,4-triazole-5-one, HTZA = tetrazole-1-acetic acid, HDNBA = 3,5-dinitrobenzoic acid), were synthesized using a microwave method with high yields. Single crystal X-ray diffraction revealed that 1 possess a 3D supramolecular structure with mononuclear units and 2 has a 2D supramolecular architecture with 1D chains. Thermoanalysis demonstrated that the two complexes have good thermostability, up to 238 °C for 1 and 270 °C for 2. The non-isothermal kinetics for exothermic processes of the complexes were studied using Kissinger's and Ozawa's methods. The calculated detonation properties and sensitivity tests showed that both complexes could be used as potential explosives. In addition, the two complexes were explored as combustion promoters to accelerate the thermal decomposition of RDX (1,3,5-trinitro-1,3,5-triazinane) using differential scanning calorimetry.
