چکیده
The mean planes of the two benzene rings in the title compound, C(17)H(16)FNO, are twisted slightly, making a dihedral angle of 7.8 (1)°. The prop-2-en-1-one group is also twisted slightly with a C-C-C-O torsion angle of -11.6 (3)°. In the crystal, weak inter-molecular C-H⋯O inter-actions link pairs of mol-ecules, forming centrosymmetric dimers.

The asymmetric unit of the title compound, C(17)H(19)NOS, contains two independent mol-ecules which differ in the dihedral angles between the five- and six-membered rings [12.52 (10) and 4.63 (11)°]. Weak inter-molecular C-H⋯O hydrogen bonds link the two independent mol-ecules into pseudocentrosymmetric dimers. In one mol-ecule, the O atom of the carbonyl group is disordered over two positions ...
