Molecular Structure and Thermal Behavior of 3,6-Dihydrazino-l,2,4,5-Tetrazine Nitrate
The single crystal of 3,6-dihydrazino-l,2,4,5-tetrazine nitrate (DHTz·HNO3) developed in binol/ethanol, is monoclinic, space group C2/c, with a=13.136(3)?, b=8.375(2)?, c=10.277(2)?, V=991.2(4)?3, β=118.748°(2), Z=4. The thermal behavior of the title compoud was studied under a non-isothermal condition by DSC techniques. The result exhibits that DHTz·HNO3 undergoes a highly exothermic decomposition reaction process under a nonlinear isotherm rate, the apparent activation energy (Ea) and pre-exponential factor (A) of the exothermic decomposition reaction are 100.71 kJ·mol-1 and 1010.83 s-1, respectively. The entropy of activation (ΔS≠), enthalpy of activation (ΔH≠) and free energy of activation (ΔG≠) are -39.57 J·mol-1·K-1, 99.87 kJ·mol-1 and 114.85 kJ·mol-1, respectively.
