A novel cuprous azide complex with the formula of [Cu2(dmpz)(N3)2]n(1, dmpz: 2,6-dimethylpyrazine) has been synthesized through hydrothermal synthesis with the reducibility of H3PO3 and structurally characterized by single-crystal X-ray diffraction method. Single-crystal X-ray diffraction analysis reveals the title complex represents a three-dimensional network structure featuring 2D [Cu N3]n plane units bridged by bridging dmpz ligands to form a 3D network. Research results reveal that 1 has lower impact sensitivity and friction sensitivity, which may be expected to become insensitive energetic material and have potential applications. Crystal data: monoclinic, space group C2/c, a = 17.8599(15), b = 8.2889(5), c = 14.8076(14) ?, β = 113.2580(10)o, V = 2014.0(3) ?3, Z = 8, S = 1.025, the final R = 0.0303, w R = 0.0825 for 1460 observed reflections with I > 2σ(I) and R = 0.0386, wR = 0.0870 for all reflections. In addition, elemental analysis, IR, and sensitivity characterization are presented.
A new cobalt(Ⅱ) coordination polymer with the formula of [Co(iqnc)2]n(1, iqnc = l-isoquinolinecarboxylate) has been synthesized through hydrothermal synthesis and structurally characterized by single-crystal X-ray diffraction method. The title coordination polymer represents a two-dimensional layer structure featuring adjacent one-dimensional [Co(iqnc)2]n chains connected with each other by uncoordinated oxygen atoms of carboxylate. Crystal data: monoclinic, space group P21/c, a = 15.4302(2), b = 5.6743(7), c = 9.2307(1) ?, β = 98.459(2)o, V = 799.41(2) ?3, Z = 2, S = 1.019, the final R = 0.0346, w R = 0.0876(I > 2σ(I)) and R = 0.0477 and wR = 0.1159 for all reflections. In addition, elemental analysis, IR, and magnetism properties are presented.
水热条件下合成了一个四唑含能配合物[Co(pzta)(H_2O)_2](pzta=5-吡嗪基四唑)。运用TG-DSC热分析仪研究了配合物的热分解行为;在非等温条件下,采用Kissinger's和Ozawa-Doyle's两种方法,对配合物进行了非等温动力学研究,得到它的表观活化能(E=153.63 k J mol-1)。利用DSC技术分析了配合物对AP和HMX热分解行为的影响,结果表明:配合物的加入对于HMX的放出的热量和峰温影响不大;使AP的分解峰温提前不多,但是加入配合物后呈现出的剧烈放热过程,放热量增加,因此配合物对AP具有较好的催化燃烧效果。
