摘要
以香兰素和邻苯二胺为原料,通过固体研磨、乙醇洗涤、甲醇重结晶的方法,合成了关环化合物1-(4-羟基-3-甲氧基苄基)-2-(4-羟基-3-甲氧基苯基)苯并咪唑,并利用X-射线单晶衍射、元素分析、红外光谱和紫外-可见光谱等手段对其进行了表征.结果表明:该化合物属于单斜晶系,空间群为P2(1)/c,晶胞参数a=7.973(16)nm,b=16.409(3)nm,c=14.323(3)nm,琢=90毅,茁=95.20(3)毅,酌=90毅;化合物分子间通过O—H…O、O—H…N和C—H…O等氢键连接形成超分子网络结构.
The 1-(4-hydroxy-3-methoxybenzyl)-2-(4-hydroxy-3-methoxyphenyl)benzimidazole is synthesized through the solid ground, washed by ethanol and recrystallized by methanol with o-phenylenediamine and 4-hydroxyl-3- methoxybenzal-dehyde as raw materials. The title compound is characterized by X-ray single-crystal diffraction, elemental analysis, IR and UV-Vis. The results show that the crystal structure of the compound belongs to monoclinic system with space group P2 (1)/c. The cell parameters are as follows: α= 7.973 (16) nm, b = 16.409(3) nm, c = 14.323(3) nm, α = 90° β = 95.20 (3)°,γ = 90°. In the crystal structure, intermolecular O-H…O, O-H…N and weak intermolecular C--H…O hydrogen bonds connect the molecules into a three- dimensional network.
