摘　　要：合成了2,6-二氨基-3,5-二硝基吡嗪-1-氧化物(LLM-105)Pb(Ⅱ)含能配合物,采用FT-IR和元素分析表征并分析了其结构,该含能盐分子式为Pb(C4H2N6O5)。测试了LLM-105 Pb(Ⅱ)含能配合物的撞击感度和摩擦感度,感度值分别为102 cm和18%。采用TG-DTG和DSC技术研究了LLM-105 Pb(Ⅱ)含能配合物的热分解行为,配合物有一个分解放热峰,峰温为240.7℃,热分解剩余残渣量为56.2%。采用TG-DTG和DSC技术研究了LLM-105 Pb(Ⅱ)含能配合物对高氯酸铵(AP)热分解的催化作用,结果表明:LLM-105 Pb(Ⅱ)含能配合物可使AP热分解速度加快,高温分解峰温提前63.8℃,对AP的热分解具有良好的催化效果。An energetic Pb（Ⅱ） complex of 2,6-diamino-3,5-dinitropyrazine-1-oxide （LLM-105） was synthesized, and its structure was characterized with FT-IR spectroscopy and elemental analysis. The chemical composition of Pb（Ⅱ） complex of LLM-105 can be recognized as Pb （C4H2N605 ）. Impact sensitivity and friction sensitivity of Pb（Ⅱ） complex of LLM-105 is 102 cm and 18% , respectively. The thermal decomposition process of the title complex and catalytic effect of Pb（Ⅱ） complex of LLM-105 on the thermal decomposition of ammonium perchlorate （AP） was studied by means of the TG, DTG and DSC. The energetic complex presents one violent exothermic peak （240.7 ℃ ） with 56.2% residues. Measurements show that the energetic complex could accelerate the thermal decomposition of AP for which the decomposition temperature is reduced by 63.8 ℃. The energetic complex has a good catalytic effect on the thermal decomposition of AP.
