A proposed correlation between coordination chemistry and deduced energetic properties (thermal behaviour, and sensitivities towards mechanical and optical stimuli) of copper(II) complexes is investigated. Starting from a system comprising Cu(ClO4)2 and either of the ligands 2-methyl-5-aminotetrazole (1, 2-MAT) or 2-methyl-5H-tetrazole (2, 2-MTZ), typically altered parameters like the metal(II) centre, ligand, or counterion were predefined. Instead, solely slight changes in ligand concentration and the solvent system were implemented in order to provide an insight into structure–property relationships of energetic coordination compounds (ECC) of this type. As a result, five highly energetic complexes [Cu(H2O)2(2-MAT)4](ClO4)2·H2O (3), [Cu(H2O)2(2-MAT)4](ClO4)2 (4), [Cu(H2O)2(2-MAT)4](ClO4)2·2 2-MAT (5), [Cu(ClO4)2(H2O)2(2-MAT)2] (6), and [Cu(H2O)2(2-MTZ)4](ClO4)2 (7) were synthesized and, except for 5, elaborately characterized. Besides structural elucidation via X-ray diffraction, NIR-spectroscopy, differential thermal analysis (DTA), standard sensitivity measurements (impact, friction, and electrostatic discharge), UV/vis-spectroscopy, and optical initiation experiments were conducted to deduce a precise relationship between coordination chemistry and the consequential energetic characteristics of these complexes.

高氯酸 铜(ii)络合物中的2-甲基取代的单四唑:操纵配位化学和衍生的能量性质

研究了配位化学与推断的铜(II)配合物的能量性质(热行为以及对机械和光学刺激的敏感性)之间的拟议相关性。从包含Cu(CLO的系统开始42和任一配体的2-甲基-5-氨基四唑(1,2-MAT)或2-甲基-5- ħ四唑(2,2- MTZ),典型地改变参数像金属(II)中心,配体或抗衡离子已预先定义。取而代之的是,仅对配体浓度和溶剂体系进行了微小的改变,以便深入了解这种类型的能量配位化合物(ECC)的结构与性质之间的关系。结果,五个高能络合物[Cu(H 2 O)2(2-MAT)4 ](ClO 42 ·H 2 O(3),[Cu(H 2 O)2(2-MAT)4 ](ClO 424),[Cu(H 2 O)2(2-MAT)4 ](ClO 42 ·2 2-MAT( 5),[Cu(ClO 4 2(H 2 O) 2(2-MAT) 2 ]( 6)和[Cu(H 2 O) 2(2-MTZ) 4 ]合成了(ClO 4 2 7),除了5以外,对其进行了详细地表征。除了通过 进行了X射线衍射,NIR光谱,差热分析(​​DTA),标准灵敏度测量(冲击,摩擦和静电放电),UV /可见光谱和光学引发实验,以推导配位化学与这些配合物的相应的能量特征。
