摘要
标题化合物C23H27O4Cl是由邻氯苯甲醛与5,5-二甲基-1,3-环己二酮在N,N-二甲基甲酰胺中反应而得。结构通过单晶X-射线衍射法测定,其晶体属于单斜晶系,空间群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,最后的偏离因子为在晶体结构中,存在两个共轭的烯醇式结构。四个C-O健长分别为1.283(2),1.285(2),1.287(3)和1.298(2)
The title compound(C23H27O4Cl) has been synthesized by reaction of 4-chlorobenzaldehydeand 5, 5-dimethyl-1, 3-cyclohexanedione in N, N-dimethylformamide and its structure was deter-mined by single crystal X-ray diffraction. The crystal is monoclinic, space group P21/a, a =The structure wassolved by direct methods, and refined by full-matrix least-squares method to a final R= 0.034and Rw=0.043. The crystal structure shows that there are two conjugated enol forms in themolecule. The C-O bond lengths are 1. 283 (2), 1. 285 (2), 1. 287 (3) and 1. 298 (2) ,re-spectively.
