title: 3-(9H-Fluoren-9-yl)-3-(4-methyl-phen-yl)-1-phenyl-propan-1-one.
abstract: In the title compound, C(29)H(24)O, the phenyl and methyl-phenyl rings are approximately perpendicular to each other, making a dihedral angle of 87.67 (10)°, and are oriented at dihedral angles of 62.49 (9) and 84.77 (7)°, respectively, to the nearly planar fluorene ring system [maximum deviation = 0.077 (2) Å] In the crystal, weak C-H⋯π inter-actions are observed.
