Abstract
A new energetic zinc-FOX-7 complex (FOX-7 = 1,1-diamino-2,2-dinitroethylene), Zn(NH3)2(FOX-7)2, was synthesized and structurally characterized by single crystal X-ray diffraction. Zn2+ was coordinated by four nitrogens from two ammonias and two FOX-7− anions, forming a distorted tetrahedron. Thermal decomposition of Zn(NH3)2(FOX-7)2 was studied by differential scanning calorimetry and thermogravimetry/differential thermogravimetry. The apparent activation energy and pre-exponential constant of the first decomposition process are 144.8 kJ M−1 and 1013.99 s−1, respectively. The self-accelerating decomposition temperature and critical temperature of thermal explosion of Zn(NH3)2(FOX-7)2 are 183.2 and 195.8 °C, respectively. The thermal stability of Zn(NH3)2(FOX-7)2 is good, but Zn(NH3)2(FOX-7)2 is still sensitive.
