چکیده
In the title compound, C16H14O4, the benzene rings are inclined at a dihedral angle of 75.14 (9)°. The torsion angle of the bridging O-C-C-O group is -76.50 (11)°. In the crystal, mol-ecules are linked by C-H⋯O hydrogen bonds, forming C(6) chains along [100]. Furthermore, C-H⋯π inter-actions and π-π stacking inter-actions [centroid-centroid distances = 3.6957 (7) and 3.6735 (8) Å] contribute to the stability of the crystal packing.
