摘要: Abstract Self-assembly of Ni(II) with 3,5-diamino-1,2,4-triazole resulted in a 3D supramolecular compound [Ni3(Hdatrz)6(fma)2(H2O)4]fma·11H2O (1) the presence coligand fumaric acid (Hdatrz = 3,5-diamino-1,2,4-triazole, H2fma = fumaric acid). X-ray structural analysis reveals that three nickel ions are bridged by six neutral Hdatrz ligands, and abundant lattice water molecules exist 1. Based on framework TG curve 1, new energetic [Ni3(Hdatrz)6(fma)2(H2O)4]fma (2) 35.5% nitrogen content was readily prepared through dehydration 1 at 398 K under N2 atmosphere. The enthalpy change reaction formation for determined to be (−23.24 ± 0.05) kJ mol−1 microcalorimetry (298.15 ± 0.01) K. Thermodynamic thermokinetic parameters k, E, n, Δ S ≠ θ , H G were obtained. Thermoanalytical kinetics 2 further investigated. sensitivity experiment results indicated more sensitive impact friction stimuli As an additive, effectively promoted thermal decomposition ammonium perchlorate (AP), which projected potential application as combustion modifier solid propellants.
