| Popis: | Two new energetic complexes base on nitrogen-rich compound 4-amino-3-(5-tetrazolate)-furazan: Cu(NH3)4 (AFT)2 (1) and Cu(C3H6N2H4)2 (AFT)2 (2) were synthesized by reaction of Cu(NO3)2·3H2O with ammonia and diaminopropane. For complexes 1 and 2, they were fully characterized by EA and FT-IR. The crystal structure of complex 1 was determined by single-crystal X-ray diffraction. X-ray single-crystal diffraction analysis revealed that the complex 1 crystallized in orthorhombic crystal system. The thermal decomposition behaviors of the two complexes were studied with DSC and TG/DTG methods. The non-isothermal kinetics parameters were calculated by the Kissinger's method and Ozawa-Doyle's method for the main exothermic decomposition processes of the title compounds. Moreover, the entropy of activation (ΔS≠), the enthalpy of activation (ΔH≠) and the free energy of activation (ΔG≠) were calculated. The specific heat capacity (Cp) and mechanical sensitivity were also investigated. |
