Abstract

The title compound, C(18)H(18)O(5), was obtained by the reaction of 4-hy-droxy-benzaldehyde with bis-(2,2-dichloro-eth-yl) ether in dimethyl-formamide. In the crystal, the mol-ecule lies on a twofold rotation axis that passes through the central O atom of the aliphatic chain, thus leading to one half-mol-ecule being present per asymmetric unit. The carbonyl, aryl and O-CH(2)-CH(2) groups are almost coplanar, with an r.m.s. deviation of 0.030 Å. The aromatic rings are approximately perpendicular to each other, forming a dihedral angle of 78.31 sh;H⋯O hydrogen bonds and C-H⋯π inter-actions help to consolidate the three-dimensional network.

摘要

标题化合物C(18)H(18)O(5)是通过4-羟基苯甲醛与双(2,2-二氯乙基)醚在二甲基甲酰胺中反应得到的。在晶体中，分子位于一条通过脂肪链中心O原子的二重旋转轴上，因此每个不对称单元中有半个分子。羰基、芳基和O-CH(2)-CH(2)基团几乎共面，均方根偏差为0.030 Å。芳环彼此近似垂直，形成78.31°的二面角。H⋯O氢键和C-H⋯π相互作用有助于巩固三维网络。
