The compound 2-(p-tolyl)-5-(3,4,5-trimethoxyphenyl)-1,3,4-oxadiazole (m.f. C18H18N2O4) was synthesized and characterized by 1H NMR, 13C NMR, MS and X-ray single crystal diffraction analysis. In the crystal structure, the two phenyl rings and the 1,3,4-oxadiazole ring are nearly coplanar with the dihedral angles 4.55, 1.13 and 3.97°. There is an offset face-to-face p-p stacking interaction between 1,3,4-oxadiazole ring planes. The compound molecules are connected through the offset face-to-face p-p stacking interactions to generate a three-dimensional network. The results of preliminary biological activity assay showed that the title compound exhibited good antibacterial activity against Staphylococcus aureus and Escherichia coli.
合成了化合物2-(对甲苯基)-5-(3,4,5-三甲氧基苯基)-1,3,4-恶二唑(m.f. C18H18N2O4),并通过1H NMR、13C NMR、MS和X射线单相表征晶体衍射分析。晶体结构中,两个苯环和1,3,4-恶二唑环几乎共面,二面角分别为4.55、1.13和3.97°。 1,3,4-恶二唑环平面之间存在偏移的面对面p-p堆积相互作用。化合物分子通过偏置面对面的p-p堆积相互作用连接起来,生成三维网络。初步生物活性测定结果表明,标题化合物对金黄色葡萄球菌和大肠杆菌具有良好的抗菌活性。
