摘要
以N,N′-二(5-四唑基)胺为含能配体设计合成了一个含能配合物[Mn(BTA)(phen)2·5H2O](1)(BTA=N,N′-二(5-四唑基)胺,phen=1,10-phenanthroline),利用元素分析,X射线单晶衍射,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对固体推进剂主要组分HMX热分解行为的影响,结果表明配合物1可以降低HMX的分解峰温.晶体学数据:单斜晶系,P2(1)/c空间群,a=1.0752(6)nm,b=2.6913(14)nm,c=1.0965(6)nm,β=107.953°,V=3.019(3)nm3,Z=4,S=1.010,最终残差因子[I>2σ(I)]R1=0.0420,wR2=0.1084,对于全部数据R1=0.0608,wR2=0.1207.
A novel energetic complex with the formula of [Mn(BTA)(phen)2·5H2O] (1) (BTA = bi(5-tetrazolyl)amine, phen=1,10-phenanthroline) has been synthesized and structurally characterized by elemental analysis, IR, thermal gravimetric analysis and single crystal X-ray diffraction methods. Crystal data: monoclinic, space group P2(1)/c, a=1.0752(6) nm, b=2.6913(14) nm, c=1.0965(6) nm, β= 107.953°, V=3.019(3) nm^3, Z=4, S= 1.010, final R indices [I〉2σ(I)] R1 =0.0420, wR2=0.1084, for all reflections R1=0.0608, wR2=0.1207. In addition, the influence on the thermal decomposition of the main component of propellant HMX by the complex 1 was studied, which reveals that the complex 1 can decrease the peak temperature of thermal decomposition of HMX.
