A new high-energy nitrogen complex [Zn (DAT) 6] (ClO4) 2 (DAT = 1,5-diaminotetrazole) was synthesized by direct method and its structure was characterized by elemental analysis and Fourier transform infrared spectroscopy . The single crystal was grown by slow evaporation solvent method, and the crystal structure was determined by single crystal X-ray diffraction. The results show that the crystal belongs to the trigonal system with a = b = 1.18398 (9) nm and c = 0.65700 (10) nm, γ = 120 °, V = 0.79760 (15) nm3 and Z = 1. There are 1 Zn2 +, 6 DAT molecules and 2 ClO-4 in the smallest asymmetric unit of the target complex. The six N atoms of DAT molecules coordinate with central Zn2 + respectively to form a six-coordinate, non-centrosymmetric, distorted octahedron structure. Differential scanning calorimetry, TG-DTPA and FTIR The thermal decomposition mechanism of the title compound and the kinetic parameters of the decomposition reaction.The sensitivity of the title complex was measured and the results show that the title complex has a certain degree of friction sensitivity.
