摘　　要：以邻香兰素和水合肼作为反应物,通过缩合反应合成了双邻香兰素缩肼席夫碱。通过红外光谱、核磁共振光谱对其进行了结构表征。通过自然挥发的方法培养了化合物的单晶,并对其进行了晶体结构解析。晶体结构结果表明,该化合物属于单斜晶系,空间群为P2_(1)/n。C…C弱相互作用对晶体结构的稳定起到十分重要的作用,每个化合物分子通过四个C…C弱相互作用促使化合物分子自组装成二维网络结构。Schiff compound based on O-vanillin was synthesized by condensation reaction of O-vanillin and hydrazine hydrate.Its structure was characterized by IR and NMR.The single crystal of the compound was cultured by natural volatilization,and its crystal structure was analyzed.The results of crystal structure show that the compound belongs to monoclinic system and its space group is P2_(1)/n.C…C short contacts play a very important role in the stability of crystal structure.Each compound molecule can self-assemble into a two-dimensional network structure through four C…C short contacts.
