Synthesis, Structure and the Influence on the Thermal Decomposition Behaviors of the Main Component of Propellant of a Energetic Complex [Ni_3(3-atrz)_6(H_2O)_6][Ni(pda)_2]_3·12H_2O

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。

A energetic complex [Ni3（3-atrz）6（H2O）4[Ni（pda）2]3·12H2O（1） （3-atrz=3-amino-1,2,4-triazole, pda =pyridine-2,6-dicarboxylic acid） was synthesized by hydrothermal method and characterized by chemical analysis, elemental analysis, single crystal X-ray diffraction, IR and thermal analysis. Structural analysis shows that the complex crystallizes in triclinic, space group P-1 and includes two different neutral structure units [Ni3 （3 - atrz）6 （H2O）6] and [Ni （pda）2], in which the 3-atrz ligand adopts a μ, - N1, N2 coordination mode and the pda ligand takes a tridentate chelate coordination mode. The effects of the complex on the thermal decomposition behaviors of the main component of propellant RDX, HMX, NC/NG and AP were tested by DSC technique.
