Abstract
To develop new series of tetrazole energetic materials, two new compounds, magnesium and calcium salts of 1, 2-bis(tetrazol-5-yl)ethane ([Mg(BTE)(H2O)4]n•nH2O and [Ca(BTE)(H2O)5]n) were prepared. Their single crystals were obtained by solvent evaporation method. The structures were fully characterized by X-ray single crystal diffraction, elemental analysis and FT-IR method. The thermal decomposition behavior of two compounds were studied by DSC and TG-DTG methods Their non-isothermal kinetic parameters were calculated by the Kissinger method and Ozawa method. Results show that [Mg(BTE)(H2O)4]n•nH2O belongs to monoclinic system, space group P21/c, cell parameters: a=9.0367(18) Å, b=9.1427(18) Å, c=7.4491(15) Å, β=103.51(3)°, Z=2. [Ca(BTE)(H2O)5]n belongs to orthorhombic system, space group Pnnm, cell parameters: a=11.205(2) Å, b=13.605(3) Å, c=7.1415(14) Å, Z=4. The temperatures of first exothermic peak for [Mg(BTE)(H2O)4]n•nH2O and [Ca(BTE)(H2O)5]n are 387.7℃ and 415.8℃, respectively.
