4‐triazole (2) were successfully synthesized and characterized by UV–vis, FTIR, 1H NMR, ESI‐MS spectra, elemental analysis, and single crystal X‐ray crystallography. The structural analysis indicates that 1 is almost a planar molecule but 2 not. The crystal structure of 1 is stabilized by two kinds of intermolecular π–π interactions and two types of intermolecular C–H···N hydrogen bonds, whereas 2 by
两种杂环化合物,2-(对-溴苯基)-5-(2-吡啶基)-1,3,4-恶二唑(1)和3-(对-溴苯基)-4-苯基-5-(2-吡啶基) ‐1,2,4-三唑(2)已成功合成并通过UV-vis,FTIR,1 H NMR,ESI-MS光谱,元素分析和单晶X射线晶体学进行了表征。结构分析表明1几乎是平面分子,而2则不是。的晶体结构1被2种分子间π-π相互作用和两种分子间C-H···Ñ氢键稳定的,而2通过三种C–H···π相互作用和三种类型的分子间C–H···N氢键形成。另外,可以在190℃的苯胺溶液中由1直接制备2,产率为70%。
