3-(9H-Fluoren-9-yl)-1,3-diphenyl­propan-1-one

In the title compound, C₂₈H₂₂O, the fluorene ring system is approximately planar [maximum deviation = 0.044 (2) Å] and forms dihedral angles of 69.88 (6) and 89.46 (6)° with the phenyl rings. The crystal packing is stabilized by weak π–π stacking inter­actions, with centroid–centroid distances of 3.7172 (13) and 3.7827 (11) Å.
