چکیده
The asymmetric unit of the title compound, C(19)H(16)FN(3)O, contains two crystallographically independent mol-ecules. The triazole rings in both mol-ecules are essentially planar with maximum deviations of 0.002 (1) and 0.001 (1) Å. The dihedral angles between the benzene and fluorophenyl rings are 79.36 (9) and 89.40 (10)° in the two molecules. In the crystal, the two independent mol-ecules are linked by C-H⋯N hydrogen bonds, forming dimers. Furthermore, the crystal structure is stabilized by C-H⋯π inter-actions.
