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

Abstract

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).

“…All the three rings (two benzene and one pyranone) are in the same plane with a benzene and pyranone ring connected through a single bond. Such bonding situations have been more likely found to have some orientations in horizontal plane [28] , [29] , [30] , [31] , [32] however, in the current case both the rings are in the same plane. This might be due to packing effects where the molecules have π-π stacking interactions that might keep these rings in the plane.…”
