Abstract

In the title molecule, C25H14O4, the fused-ring system consisting of four rings is approximately planar, with a dihedral angle of 9.62 (5)degrees 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)degrees with the mean plane of the fused-ring system. A weak C-H center dot center dot center dot O interaction organizes the molecules into a helical chain along the b axis. In addition, there is a pi-pi stacking interaction between the five-membered rings of adjacent fused-ring systems, with a centroid-centroid distance of 3.666 (1) angstrom.
