Abstract

The title compound, C(30)H(22)O, does not form face-to-face π-π inter-actions despite the presence of four phenyl rings within the compound. Instead weak C-H⋯π inter-actions occur between adjacent mol-ecules, with C⋯C contact distances in the range 3.633 (4)-3.974 (4) Å. The ketone O atom also takes part in a weak C-H⋯O inter-action. The three pendant phenyl rings are twisted relative to the central cyclopentadiene ring by 17.82 (17), 29.63 (14) and 61.57 (9)°, while the phenylmethanone is nearly orthogonal, the angle between planes being 87.77 (9)°.
