摘要 设计合成了含能配合物[Pb(AZTZ)(bpy)(H2O).2H2O]n(1)(AZTZ=5,5′-偶氮四唑阴离子,bpy=2,2′-联吡啶),用X射线单晶衍射法测定了其分子结构.该晶体属三斜晶系,P1空间群,a=0.7341(6)nm,b=1.0050(8)nm,c=1.3367(1)nm,α=95.354(1)°,β=101.450(1)°,γ=101.233(1)°,V=0.8927(1)nm3,Z=2,S=1.030.利用元素分析、红外光谱以及热重分析等手段对标题化合物进行了表征,并研究了配合物(1)对固体双基推进剂的燃烧催化作用.结果表明,配合物(1)可以有效地提高固体双基推进剂的燃速. A novel energetic complex with a formula of [ Pb (AZTZ) (bpy) ( H2 O) · 2H2O ] n ( 1 ) ( AZTZ = 5,5'-azotetrazole dianion, bpy = 2,2' bipyridine ) was synthesized and its structure was characterized by elemental analysis, IR, thermalgravimetric analysis and single crystal X-ray diffraction method. Crystal data: triclinic system, space group P1^-, a=0.7341(6) nm, b = 1.0050(8) nm, c = 1.3367(1) nm, α = 95.354(1)°, β =101. 450(1)°, γ = 101. 233(1)°, V=0. 8927(1) nm3, Z =2, S = 1.030, final R indices [1〉2σ(I) ], R1 =0. 0301, wR2 =0. 0605 , for all reflections R1 =0. 0351, wR2 =0. 0630. In addition, the catalytic performance of complex 1 on the combustion of solid double-based propellant is presented, which shows that complex 1 can enhance the burning-rate of solid double-based propellant.
