    摘要:

    合成了一种新型含能锌配合物[Zn(en)3](FOX-7)2,并测定其晶体结构。该晶体属单斜晶系,空间群C2/c,晶胞参数为:a=0.77170(16) nm, b=1.6720(3) nm, c=1.6996(3) nm, β=94.333(3)°, V=2.1867(7) nm3, Z=4, μ=1.194 mm-1, F(000)=1112, Dc=1.628 g·cm-3, R1=0.0359, wR2=0.0955。中心锌离子与三个乙二胺分子中的六个N原子发生配位,形成了一个畸变的八面体结构, FOX-7-阴离子并未与中心Zn2+发生配位作用, 而以外界离子的形式存在于分子结构中。用非等温DSC,TG/DTG法研究了[Zn(en)3](FOX-7)2的热分解行为,其自加速分解温度和热爆炸临界温度分别为167.1 ℃与168.8 ℃。[Zn(en)3](FOX-7)2的热稳定性低于Zn(NH3)2(FOX-7)2。[Zn(en)3](FOX-7)2的撞击感度约为20.6 J。

    Abstract:

    A new energetic Zn-FOX-7 complex [Zn(en)3](FOX-7)2 was firstly synthesized and characterized by X-ray diffraction (FOX-7, 1, 1-diamino-2, 2-dinitroethylene). The crystal is monoclinic, space group C2/c with crystal parameters of a=0.77170(16) nm, b=1.6720(3) nm, c=1.6996(3) nm, β=94.333(3)°, V=2.1867(7) nm3, Z=4, μ=1.194 mm-1, F(000)=1112, Dc=1.628 g·cm-3, R1=0.0359, wR2=0.0955. Thermal decomposition of [Zn(en)3](FOX-7)2 was studied by differential scanning calorimetry and thermogravimetry methods. Results show that central Zn2+ ion is coordinated by six N atoms from three ethylenediamine molecules, which form a distorted octahedral structure, and while FOX-7- anion has no coordination with central Zn2+ ion. The self-accelerating decomposition temperature and critical temperature of thermal explosion of [Zn(en)3](FOX-7)2 are 167.1 ℃ and 168.8 ℃, respectively. [Zn(en)3](FOX-7)2 exhibits lower thermal stability than Zn(NH3)2(FOX-7)2. The impact sensitivity of [Zn(en)3](FOX-7)2 is about 20.6 J.
