Three novel rare-earth, nitrogen-rich and oxygen heterocyclic supramolecular complexes, namely [Nd (BTF)₂(H₂O)₅]_n, [Sm(BTF)₂(H₂O)₅]_n, and [Eu(BTF)₂(H₂O)₅]_n, were synthesized. A single crystal was obtained by the solvent evaporation method, and the structure and coordination mode of metal complexes were determined by single crystal X-ray diffraction. Results show that the supramolecular complexes contain many hydrogen bonds and thus have good thermal stability (T_dec > 540 K). The thermal decomposition of ammonium perchlorate (AP) catalyzed by the complexes was investigated by differential thermal analysis, which reveals a pre-eminent catalytic effect on AP. The high temperature decomposition peak of AP can be advanced by nearly 90 K at the amount of added complexes of 10 wt%, and the activation energy of AP descent range is from 70 to 150 kJ/mol. The other properties were fully characterized through elemental analysis and Fourier transform infrared spectroscopy.

三种新型稀土富氮氧杂环超分子配合物，即[Nd (BTF) ₂ (H ₂ O) ₅ ] _n、[Sm(BTF) ₂ (H ₂ O) ₅ ] _n和[Eu( BTF) ₂ (H ₂ O) ₅ ] _n被合成。采用溶剂蒸发法获得单晶，通过单晶X射线衍射确定金属配合物的结构和配位方式。结果表明，超分子配合物含有许多氢键，因此具有良好的热稳定性（T _dec > 540 K)。通过差热分析研究了由配合物催化的高氯酸铵（AP）的热分解，揭示了对AP的显着催化作用。在配合物添加量为10 wt%时，AP的高温分解峰可提前近90 K，AP下降范围的活化能为70～150 kJ/mol。其他性质通过元素分析和傅里叶变换红外光谱得到充分表征。
