Abstract
Three chelating energetic materials (CEM), [Co(SCZ)2(H2O)2](TNR)(H2O)2 (1), [Ni(SCZ)2(H2O)2](TNR)(H2O)2 (2) and [Zn(SCZ)2(H2O)2](TNR)(H2O)2 (3, SCZ=semicarbazide, H2TNR=styphnic acid), were synthesized and characterized by elemental analysis, FTIR spectroscopy and single-crystal X-ray diffraction analysis. Single-crystal X-ray diffraction analysis revealed that 1 mainly exhibits swathe construction, whereas 2 and 3 manifest grating structure. Thermal decomposition behaviors of 1–3 were studied by differential scanning calorimetry (DSC). The critical temperature of thermal explosion, the entropy of activation (ΔS≠), the enthalpy of activation (ΔH≠), and the free energy of activation (ΔG≠) were also calculated. Sensitivity tests revealed that 1–3 are insensitive to mechanical stimuli, and that the grating structure (2 and 3) shows better shock resistance and flame retardant property than the swathe construction (1) at the molecular level.
