• A new energetic zinc-FOX-7 complex (FOX-7 = 1,1-diamino-2,2-dinitroethylene), Zn(NH 3 ) 2 (FOX-7) 2 , was synthesized and structurally characterized by single crystal X-ray diffraction. Zn 2+ was coordinated by four nitrogens from two ammonias and two FOX-7 − anions, forming a distorted tetrahedron. Thermal decomposition of Zn(NH 3 ) 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 10 13.99  s −1 , respectively. The self-accelerating decomposition temperature and critical temperature of thermal explosion of Zn(NH 3 ) 2 (FOX-7) 2 are 183.2 and 195.8 °C, respectively. The thermal stability of Zn(NH 3 ) 2 (FOX-7) 2 is good, but Zn(NH 3 ) 2 (FOX-7) 2 is still sensitive.
