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 a...

The asymmetric unit of the title compound, C(19)H(17)N(3)O, contains two independent mol-ecules. In one mol-ecule, the essentially planar triazole ring [maximum deviation = 0.003 (2) Å] forms dihedral angles of 5.57 (12) and 87.51 (12)° with the two phenyl rings, while in the other mol-ecule [maximum deviation in triazole ring = 0.001 (2) Å] these angles are 1.55 (10) and 82.73 (11)°. The dihed...

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, ...

In the title mol-ecule, C(22)H(16)N(2)O, the phenyl ring is twisted slightly with respect to the plane of the central pyrazole ring [dihedral angle = 14.8 (2)°]; the central ring is connected to the naphthyl ring through a -CH=CH-C(=O)- fragment, whose C=C double bond has an E configuration. The pyrazole ring and naphthalene ring system are twisted by 46.3 (1)°. Weak inter-molecular C-H⋯O hydro...

The mol-ecule of the title chalcone derivative, C(19)H(15)NO, exists in a trans configuration with respect to the C=C double bond. The mol-ecule is slightly twisted with a dihedral angle of 6.12 (12)° between the benzene ring and the naphthalene ring system. The prop-2-en-1-one bridge is nearly planar, with an r.m.s. deviation of 0.0194 (2), and makes dihedral angles of 8.05 (19) and 11.47 (18)...
