title: 3-(9H-Fluoren-9-yl)-1,3-diphenyl-propan-1-one.
abstract: In the title compound, C(28)H(22)O, 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 inter-actions, with centroid-centroid distances of 3.7172 (13) and 3.7827 (11) Å.
