formula. The thermal stability has been studied by the TGA method. Based on the results of the data obtained, the following conclusions can be drawn: (i) the structure and composition of the product is affected not only by the ratio of reagents but also by the choice of solvent for the reaction; (ii) the resulting complex compounds have high thermal stability (mass loss begins only at >250°C); (iii) the band
摘要 Bismuth(III) 卤化物与 1-ethyl-3-methylpyridinium (1-Et-3-MePy) 3 [Bi 2 I 9 ] ( 1 ) 和 (1-Et-3-MePy) 3 [Bi 3 I 12 ]络合物( 2 ) 已合成 BiI 3在有机溶剂中与 1-乙基-3-甲基碘化吡啶反应,并通过 X 射线衍射分析表征。样品的纯度已通过 X 射线粉末衍射分析得到证实。记录了漫反射光谱,并使用经典的 Kubelka-Munk 公式估算了带隙。热稳定性已通过TGA方法进行了研究。根据所得数据的结果,可以得出以下结论: (i) 产物的结构和组成不仅受试剂比例的影响,还受反应溶剂选择的影响;(ii) 所得复杂化合物具有高热稳定性(质量损失仅在 >250°C 时开始);(iii) 化合物1和2的带隙分别为 2.11 和 1.96 eV 。
