The title compound, C12H10O5, was prepared as part of our study on obtaining pure regioselective Friedel-Crafts acetyl-ation products. The mol-ecule is planar with no hydrogen bonds found in the crystal structure. The mol-ecules are stacked together through π-π inter-actions (centroid-centroid distance = 3.655 Å), with the stacks of mol-ecules forming a zigzag packing arrangement stabilized by van der Waals force...
