制备了含能配合物[Ni3(3–atrz)6(H2O)6][Ni(pda)2]3·12H2O(1)(3-atrz=3-氨-1,2,4-三唑,pda=吡啶-2,6-二甲酸),利用化学分析、元素分析、X–射线单晶衍射、红外光谱以及热重分析等手段对化合物进行了表征。结构分析表明,配合物(1)属于三斜晶系,P-1空间群,配合物的分子结构中存在两种不同类型的中性结构单元:[Ni3(3-atrz)6(H2O)6]和[Ni(pda)2],其中配体3-atrz-采取μ–N1,N2配位模式,配体pda2-采用三齿螯合配位模式。借助DSC实验技术研究了配合物对推进剂主要组份黑索金(RDX)、奥克托金(HMX)、吸收药(NC/NG)和高氯酸铵(AP)热分解行为的影响。
The complex of [Ni3 (3-atrz) 6 (H2O) 6] [Ni (pda) 2] 3 · 12H2O (1) (3-atrz = pda = pyridine-2,6-dicarboxylic acid). Compounds were characterized by chemical analysis, elemental analysis, X-ray single crystal diffraction, infrared spectroscopy and thermogravimetric analysis. The structural analysis shows that the complex (1) belongs to the triclinic and P-1 space group. There are two different types of neutral structural units in the molecular structure of the complex: [Ni3 (3-atrz) 6 ] And [Ni (pda) 2], in which the ligand 3-atrz- takes the μ-N1 and N2 coordination modes and the ligand pda2- adopts tridentate chelation coordination mode. The effects of the complexes on the pyrolysis behavior of the major components of propellants RDX, NCX, NC / NG and ammonium perchlorate (AP) were investigated by means of DSC.
