In the title molecule, C 12 H 10 O 4 , the lactone and benzene rings are coplanar, while the plane of the acetyl substituent is rotated by 12.26 (9) from the molecular plane. The molecules stack throughinteractions along [100] and these stacks are laterally connected by C-HÁ Á ÁO hydrogen bonds alon
