A New Nickel(Ⅱ) Coordination Compound Constructed by Pyridyl-triazole and Oxybis (Benzoic Acid): Synthesis, Crystal Structure and the Effect on the Thermal Decomposition of Ammonium Perchlorate
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 H2oba=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)Å, β=114.0110(10)°, V=2396.7(4)Å3, 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 H2oba 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.
