摘要：A new energetic complex, Ni（3,4’-Hbpt）2（Hoba）2（H2O）2（3,4’-Hbpt = 3-（3-pyridyl）-5-（4’-pyridyl）-1-H-1,2,4-triazole and H2 oba = 4,4’-oxybis（benzoic acid））, has been synthesized by hydrothermal reaction and characterized by elemental analysis, IR spectroscopy, single-crystal X-ray diffraction, thermogravimetric analyses and X-ray powder diffraction. Single-crystal X-ray diffraction analysis indicates that the complex belongs to the monoclinic system, space group P21/c with a = 10.2357（9）, b = 24.594（2）, c = 10.4225（9） A, β = 114.0110（10）°, V = 2396.7（4） A3, Dc =1.460 g/cm3, μ = 0.482 mm-1, Mr = 1053.63, F（000） = 1088, Z = 2, the final R = 0.0358 and wR =0.0973 with I > 2σ（I）. Both 3,4’-Hbpt and H2 oba ligands adopt monodentate modes linking one Ni（II）ion to form a 0D motif. Furthermore, the 0D motifs are linked into a 3D supramolecular architecture with hydrogen bonds. In addition, the catalytic performance for thermal decomposition of the efficacy of ammonium perchlorate（AP） is explored by differential scanning calorimetry（DSC）,which indicates that the complex is a good candidate for a promoter of the thermal decomposition of ammonium perchlorate.
