5-溴-2-羟基苯基苯甲酮苯甲酰腙的合成及晶体结构

摘要

The N' -[ (E)-1-(5-Bromo-2-Hydroxyphenyl)ethylidene] benzohy-drazide was synthesized by the reaction of 1-(5-bromo-2-hydroxyphenyl)ethanone and benzohydrazide. The crystal structure of the compound was characterized by X-ray diffraction. It was assigned to monoclinic crystal system, space group P2 (1)/n, cell data:a=17.505(5) nm,α=90.00°,b =13.761(4)nm,β =94.546(6)°,c =7.219(2)nm,γ =90.00°. V=1 733.4(9)nm3 ,Z =4,μ =2.387mm-1 ,Dc = 1.515mg/m3 ,F(000) =672, Final R indices [I ＞2sigma(I)]R1 =0.043 9,wR2 =0.081 3 R1 =0. 105 1 [I ＞2sigma(I)], wR2 =0.100 7 (all data).%由5-溴-2-羟基苯基苯甲酮和苯甲酰肼通过缩合反应,合成了一种新的芳香酰腙化合物:5-溴-2-羟基苯基苯甲酮苯甲酰腙.通过X射线单晶衍射对该化合物进行晶体结构的表征.研究表明,该酰腙为单斜晶系,空间群为P2(1)/c,晶胞学数据为a=17.505(5)nm,α=90.00°,b=13.761(4)nm,β=94.546(6)°,c=7.219(2)nm,γ=90.00°.V=1733.4(9)nm3,Z=4,μ=2.387mm-1,Dc=1.515mg/m3,F(000)=672,FinalRindices[Ⅰ＞2sigma(Ⅰ)]R1=0.0439,wR2=0.0813 R1=0.1051[Ⅰ＞2sigma(Ⅰ)],wR2=0.1007(all data).
