三唑类含能配合物在含能材料领域受到广泛关注.利用溶液法合成了一例含能配合物[Cd(Hatzc)2(H2O)](LH1),其中H2atzc=3-羧基-5-氨基-1,2,4-三唑,并用X射线单晶衍射、元素分析、红外光谱等手段进行表征.单晶结构分析结果表明LH1属于单斜晶系,空间群为P21/n,呈一维链状结构,通过氢键相互作用形成三维超分子结构.LH1的爆速(D=10.4 km·s-1)、爆压(p=55.2 GPa)、爆轰能量(16.51 kJ·g-1)和密度(2.363 g·cm-3)均优于大多数含能配合物.撞击感度(>40 J)和摩擦感度(>360 N)表明LH1对撞击和摩擦的敏感性较低.高氯酸铵(AP)的催化热分解结果表明,在LH1的催化作用下,AP的高温分解峰提前38℃,释放的热量在较短的时间增加0.46 kJ·g-1,说明LH1对AP热分解具有良好的催化效果.
Triazole-derived energetic complexes have paid significant attention in the field of energetic materials.An energetic complex[Cd(Hatzc)2(H2O)](LH1)(H2atzc=3-carboxyl-5-amino-1,2,4-triazole)was synthesized and ful-ly characterized by single crystal X-ray diffraction,elemental analysis,infrared spectral analysis,and thermogravi-metric analysis.LH1 belongs to the monoclinic system,space group P21/n.The structural analyses illustrate that LH1 exhibits a 1D chain,which is linked by hydrogen-bonding interactions to give a 3D supramolecular architec-ture.Complex LH1 had high detonation velocity(D=10.4 km·s-1),detonation pressure(p=55.2 GPa),energy of deto-nation(16.51 kJ·g-1),and density(2.363 g·cm-3),which were superior to most of the energetic compounds.The impact sensitivity(>40 J)and friction sensitivity(>360 N)reveal that LH1 is less sensitive to impact and friction.The results of the catalytic thermal decomposition of ammonium perchlorate(AP)show that LH1 decreased the higher thermal decomposition temperature of AP by 38℃and increased the exothermic quantity of decomposition by 0.46 kJ·g-1 in a short time,which showed a good catalytic effect on the thermal decomposition of AP.CCDC:2100672.
