【摘要】 A new energetic complex,[Co(3,3?-Hbpt)(Htm)]·H2O(1,3,3?-Hbpt = 3,5-bis(3-pyridyl)-1H-1,2,4-triazole and H3tm = trimesic acid),has been synthesized by hydrothermal reactions and characterized by single-crystal X-ray diffraction,elementary analysis,IR spectroscopy,thermogravimetric analysis and X-ray powder diffraction. Single-crystal X-ray diffraction indicates that the complex belongs to triclinic system,space group P 1 with a = 10.0911(1),b = 10.2573(1),c = 10.6393(1) ?,α = 103.793(2),β = 101.041(2),γ = 107.918(3)o,V = 974.9(2) ?3,Z = 2,Dc = 1.732 g·cm-3,μ = 0.941 mm-1,Mr = 508.31,F(000) = 518,the final R = 0.0523 and wR = 0.0935 with I > 2σ(I). In the title complex,Co(Ⅱ) ions are connected by Htm2-anions generating 1D ladder-like chains which are linked by 3,3?-Hbpt to form 1D cages. In addition,the thermal decomposition of ammonium perchlorate(AP) with complex 1 was explored by differential scanning calorimetry(DSC). AP is completely decomposed in a shorter time in the presence of complex 1,and the decomposition heat of the mixture is 2.531 kJ·g-1,significantly higher than that of pure AP. By Kissinger’s method,the ratio of Ea/ln(A) is 11.05 for the mixture,which indicates that complex 1 shows good catalytic activity toward the AP decomposition.
