【 摘 要 】
In the title molecule, C25H14O4, the fused-ring system consisting of four rings is approximately planar, with a dihedral angle of 9.62 (5)° between the planes of the indene ring system and the benzene ring. The dihydroindene-1,3-dione unit makes a dihedral angle of 63.50 (2)° with the mean plane of the fused-ring system. A weak C—H⋯O interaction organizes the molecules into a helical chain along the b axis. In addition, there is a π–π stacking interaction between the five-membered rings of adjacent fused-ring systems, with a centroid–centroid distance of 3.666 (1) Å.
