The title compound, C30H22O, does not form face-to-face pi-pi interactions despite the presence of four phenyl rings within the compound. Instead weak C-H center dot center dot center dot pi interactions occur between adjacent molecules, with C center dot center dot center dot C contact distances in the range 3.633 (4)-3.974 (4) angstrom. The ketone O atom also takes part in a weak C-H center dot center dot center dot O interaction. The three pendant phenyl rings are twisted relative to the central cyclopentadiene ring by 17.82 (17), 29.63 (14) and 61.57 (9)degrees, while the phenylmethanone is nearly orthogonal, the angle between planes being 87.77 (9)degrees.
