摘　　要：摘要:标题化合物C23H26BrNO2是由4-溴苯甲醛、5,5-二甲基-1,3-环己二酮(哒米酮)和NH4OAc在无溶剂条件下,80℃加热反应而得,结构通过单晶X射线衍射法确定,其晶体属正交晶系,空间群Pna2(1),Mr=428.36,a=1.408 9 nm,c=1.085 6(3)nm,V=2.154 7(9)nm3,Z=4,Dc=1.320 g/cm3,μ=1.924 mm-1,F(000)=888,晶体结构用直接法解出,使用全矩阵最小二乘法对原子参数进行修正,最终的偏离因子为R=0.040 2,Rw=0.069 9.The title compound （C23H26BrNO2） has been synthesized by the reaction of 4-bromobenzaldehyde and 5,5-dimethylcyclohexane-1,3-dione with NH4OAc under solvent-free condition at 80℃. And its structure was determined by single-crystal X-ray diffraction. The crystal is orthorhom- bic, space group Pna2（1） with Mr =428.36, a= 1. 408 9 nm, c= 1. 085 6（3） nm, V= 2. 154 7（9） nm^3 , Z=4, methods and Dc = 1. 320 g/cm^3 ,μ = 1. 924 mm^-1 , F（000） = 888. The structure was solved by direct refined by the method of full-matrix least squares to the final R=0. 040 2 and Rw =0. 069 9.
