Main observation and conclusionrnIn this study,four new energetic complexes (1) [Cu(vimi)4]DCA2,(2) [Co(vimi)4]DCA2,(3) [Ni(vimi)4]DCA2,and (4) [Cu(vimi)4]CBH2 (vimi:1-vinylimidazole,DCA:dicyanamide anion,CBH:cyanoborohydride anion) were prepared,and their structures were characterized via single-crystal X-ray diffraction,elemental analysis,and Fourier-transform infrared spectroscopy.The catalytic effects of the complexes on ammonium perchlorate thermal decomposition were studied via thermal analysis methods,including differential scanning calo-rimetry (DSC) and thermogravimetric analysis (TGA).Among the complexes,complex 2 showed the best catalytic performance.The two decomposition peaks in the DSC curve of the pure ammonium perchlorate-low-temperature decomposition (LTD) peak:295 ℃and high-temperature decomposition (HTD) peak:418 ℃-were merged into a lower decomposition peak (325 ℃) in the curve of AP with complex 2.Moreover,the heat released by ammonium perchlorate with complex 2 (1661.7 J g-1) was significantly higher than that released by the pure ammonium perchlorate (814.5 J g-1).The kinetic parameters calculated using Kissinger\'s method revealed that the complexes had a significant effect on the activation energy of ammonium perchlorate decomposition (223.5 kJ mol-1),and complex 2 lowered the activation energy to 115.6 kJ mo-1.The results indicate that complex 2 is a potential energetic additive for ammonium perchlorate-based solid propellants.
