Abstract

With respect to the triazole ring in the title compound, C19H16FN3O, the p-tolyl ring is inclined [dihedral angle = 51.79 (11)°], whereas the chalcone residue is almost coplanar [O-C-C-N and C-C-C-C torsion angles = -178.71 (19) and 178.42 (18)°, respectively]. The conformation about the C=C bond [1.328 (3) Å] is E, and the triazole methyl group and the carbonyl O atom are syn. In the crystal, centrosymmetrically related mol-ecules are connected by π-π inter-actions between the triazole and p-tolyl rings [centroid-centroid distance = 3.6599 (12) Å] and these are linked into a three-dimensional architecture by C-H⋯N and C-H⋯π inter-actions.
