subsequent hydrolysis in water at 100 °C. The versatility of 1 allows its application as starting material for a broad range of different materials. It was used for the preparation of both various salts and cocrystalline materials incorporating varying amounts of the TATOT moiety. Furthermore, H2EDN was successfully applied in the concept of energetic coordination compounds (ECCs) resulting in five copper(II)
以简单的方式制备乙二胺(H 2 EDN,1),方法是在0°C下使用100%HNO 3直接硝化2-咪唑啉酮,然后在100°C的水中水解,从而以较高的总产率制备乙二胺。多功能性1使其可用作各种不同材料的起始材料。它用于制备各种盐和结合了不同量TATOT部分的共晶材料。此外,H 2EDN已成功地应用于高能配位化合物(ECCs)的概念中,产生了五种铜(II)和两种银(I)配合物。给出了直接沉淀或缓慢结晶17种不同盐类(包括几种碱金属,碱土金属,银和富氮样品)的反应路径。通过低温单晶X射线衍射,元素分析(EA),红外光谱,差热分析(DTA)和热重分析(TGA)对这些物质进行了广泛表征,证明了它们的高热稳定性,尤其是碱盐。此外,1和所有盐的特征在于1 H,13 C和14 N NMR,而1还使用了有益的1 H- 15 N HMBC NMR光谱进行了研究。使用BAM 1-out-6方法确定了根据BAM

dicyanamide anion, was investigated as a building block in various energetic materials. Apart from nonenergetic complexes, only the use in ionic liquids has been investigated so far. Consequently, the focus in this work was on the synthesis of energetic coordination compounds (ECC) involving tetrazole ligands as well on nitrogen-rich salts, which includes not only ammonium but also hydrazinium, hydroxylammonium
在这项工作中,阴离子硝基氰胺(NCA -),作为二硝胺和双氰胺阴离子之间的交叉,被研究作为各种高能材料的组成部分。除了非能量配合物外,目前仅研究了在离子液体中的应用。因此,这项工作的重点是合成涉及四唑配体以及富氮盐的高能配位化合物 (ECC),其中不仅包括铵,还包括肼、羟铵和三氨基胍。在盐的形成过程中,还特别关注与氮碱形成加合物的可能性。这在 IR 和 NMR 光谱的帮助下得到了证明。络合产生了两种银 (I) 和九种铜 (II) 络合物,不仅在它们的配位几何学方面,而且在它们的能量特性方面也进行了研究。使用 CHNO 元素分析检查每种化合物的纯度。在某些情况下,进行 X 射线衍射实验以了解它们的最终成分。热稳定性测量使用差热分析 (DTA) 进行,对于选定的物质,使用热重分析 (TGA) 进行。根据 BAM (Bundesanstalt für Materialforschung and -prüfung)

Dinitraminic acid (HN(NO2)2, HDN) was prepared by ion exchange chromatography and acid-base reaction with basic copper(II) carbonate allowed the in situ preparation of copper(II) dinitramide, which was reacted with twelve nitrogen-rich ligands, for example, 4-amino-1,2,4-triazole, 1-methyl-5H-tetrazole, di(5H-tetrazolyl)-methane/-ethane/-propane/-butane. Nine of the complexes were investigated by low-temperature

Single crystals of the complex were grown in situ from a solution of the ligand and iron(II) tetrafluoroborate. The X-ray structure determinations of both the high spin as well as the low spin state of the compound revealed a solid state structure, which is comparable to that of
