Abstract
- The asymmetric unit of the title compound, C22H14O6, consists of two independent molecules differing in the orientations of the ester groups. In one molecule, the two terminal benzene rings are inclined to the central benzene ring by 4.99 (13) and 77.46 (13)°, while in the other the corresponding angles are 11.03 (13) and 88.09 (12)°. In the crystal, molecules are connected into a ribbon structure running along [101]viaC—H...O and C—H...π interactions. Adjacent ribbons are further linked by additional C—H...O and C—H...π interactions. The crystal studied was a non-merohedral twin [twin law (0.986 − 0.073 − 0.008, 0.323 1.036 0.148, −0.121 − 0.102 0.942)], the ratio of components being 0.937 (4):0.063 (4).
