1,1′-{2,2′-[1,4-Phenylenebis(methylene)]bis(oxy)bis(2,1-phenylene)}diethanone

Abstract

The asymmetric unit of the title compound, C24H22O4, contains one half-molecule, the other half being generated by a crystallographic center of inversion. The central benzene ring makes a dihedral angle of 72.49 (5)° with the terminal benzene ring. In the crystal, adjacent molecules are linked through C—H...O interactions, forming a sheet structure parallel to the bc plane. The sheets are stacked along the a axis via π–π interactions formed between the terminal benzene rings [centroid–centroid separation = 3.7276 (6) Å].
