中文摘要：
以三苯胺为原料，通过改进的乌尔曼反应高效地合成了三-（4-吡唑基）苯基胺（1），其结构经X-射线单晶衍射仪，^1H NMR，IR，MS和元素分析表征。1属于正交晶系，Pccn空间群，晶胞参数：a=23．394（7）A，b=34．021（9）A，c=11．719（3）A。分子间通过氢键和弱的π…π作用相互连接。
英文摘要：
Tris-（4-pyrazolyl）phenylamine （1） was efficiently synthesized from trisphenylamine by improved Ullmann reaction. The structure was characterized by single crystal X-ray diffraction, ^1H NMR, IR, MS and elemental analysis. 1 belongs to orthorhombie system with space group Pccn, a = 23. 394 （7） A, b = 34. 021 （9）A, c = 11.719 （3）A. There are weak hydrogen bonds and π - π interactions between molecules in the crystal.
