Diethyl 4,4′-(ethane-1,2-diyldioxy)dibenzoate

Abstract

The title compound, C20H22O6, was obtained by the reaction of ethyl 4-hy­droxy­benzoate with 1,2-dichloro­ethane in dimethyl­formamide. The mol­ecule lies around the crystallographic inversion center at (0,0,0), with the asymmetric unit consisting of one half of the mol­ecule. The two ethyl groups are in trans positions. The ethyl, carboxyl, aryl and O—CH2 groups are coplanar with an r.m.s. deviation of 0.0208 (9) Å. The whole mol­ecule is planar with an r.m.s. deviation of 0.0238 (9) Å for the 19 atoms used in the calculation and 0.0071 (9) Å for the two aryl groups in the mol­ecule. A weak inter­molecular C—H⋯O hydrogen bond and a C—H⋯π inter­action help to consolidate the three-dimensional network.
