In the title compound, C(14)H(10)O(2), the five-membered ring of the inden-1-one residue is almost planar (r.m.s. deviation = 0.035 Å). A twist about the single bond linking the two residues is evident [C-C-C-C torsion angle = -13.2 (5)°]. The three-dimensional architecture is stabilized by C-H⋯O (involving the trifurcated carbonyl O atom), C-H⋯π and π-π inter-actions [between the five- and six-membered rings of inden-1-one residues; ring centroid-centroid distance = 3.7983 (17) Å]. The sample studied was a non-merohedral twin; the minor component refined to approximately 36%.
