4-(4-Fluoro­benzo­yl)-3-phenyl-3,4-di­hydro­naphthalen-1(2H)-one

In the title compound, C₂₃H₁₇FO₂, the cyclo­hexenone ring has an envelope conformation, the flap atom being the C atom to which the phenyl ring is attached. The 4-fluoro­benzoyl ring and the phenyl ring are inclined to one another by 28.77 (7)°, and by 52.00 (7) and 44.77 (7) °, respectively, to the aromatic ring fused to the cyclo­hexenone ring. In the crystal, mol­ecules are linked via C—H...O hydrogen bonds, forming a two-dimensional network lying parallel to (100).
