A novel nitrogen and oxygen rich chelating energetic material (CEM) Zn(SCZ)2(H2O)2·2HTNR (1, SCZ = semicarbazide, TNR = styphnic acid) was prepared and characterized by elemental analysis, IR spectra and differential scanning calorimetry (DSC). Its crystal structure was determined through X-ray single crystal diffraction at 153(2) K. The crystal belongs to triclinic. Space group is P-1 with crystal parameters of the unit cell dimensions: a = 0.8284(2) nm, b = 1.1848(4) nm, c = 1.3411(4) nm, α = 99.617(4)°, β = 92.593(4)°, γ = 97.148(4)°, V = 1.2642(6) nm3, Z = 2 and Dc =1.943 g·cm–3. The kinetic parameters of the first exothermic process of 1 were studied by the Kissinger's method and Ozawa-Doyle's method. Sensitivity tests revealed that 1 is insensitive to mechanical stimuli. Energy of combustion and enthalpy of formation of 1 were calculated. [ABSTRACT FROM AUTHOR]
