A novel manganese complex Mn(2)(DAT)(2)Cl(4)(H(2)O)(4), where DAT is 1,5-diaminotetrazole, was synthesized by the reaction of manganese(II) chloride tetrahydrate and 1,5-diaminotetrazole (DAT) in ethanol, and characterized by elemental analysis, FT-IR spectroscopy. The crystal structure was determined through X-ray single crystal diffraction. The molecular unit of Mn(2)(DAT)(2)Cl(4)(H(2)O)(4) has a distorted octahedral structure, containing two central manganese cations, which coordinated by a mono-dentate terminal chloride, a bulky DAT ligand and two water molecules, and linked by two bidentate bridging chloride ligands. There are two main exothermic peaks and one endothermic peak in the thermal decomposition process, investigated by differential scanning calorimetry (DSC) and thermo-gravimetric analysis (TGA), the final residue of the title compound at 600 degrees C is MnO. The kinetic parameters of the endothermic process and two main exothermic processes were studied by applying the Kissinger's and Ozawa-Doyle's methods.
一种新型的锰配合物 Mn(2)(DAT)(2)Cl(4)(H(2)O)(4)，其中 DAT 是 1,5-二氨基四唑，通过在乙醇中反应二水合氯化锰和 1,5-二氨基四唑（DAT）合成，并通过元素分析和傅里叶变换红外光谱（FT-IR 光谱）进行了表征。通过 X 射线单晶衍射确定了晶体结构。Mn(2)(DAT)(2)Cl(4)(H(2)O)(4)的分子单元具有扭曲的八面体结构，包含两个中心锰阳离子，由单齿末端氯离子、体积庞大的 DAT 配体和两个水分子配位，并由两个桥联的二价氯离子连接。在差示扫描量热法（DSC）和热重分析（TGA）研究中，该配合物的热分解过程中有两个主要的放热峰和一个吸热峰，标题化合物在 600°C 时的最终残余物为 MnO。通过应用 Kissinger 和 Ozawa-Doyle 方法研究了吸热过程和两个主要放热过程的动力学参数。
