In the title compound, C(10)H(9)F(2)N(3)O, the dihedral angle between the mean planes of the triazole and benzene rings is 20.6 (2)°. In the crystal, mol-ecules are linked by strong O-H⋯ N hydrogen bonds into chains with graph-set notation C(9) along [100]. Weak C-H⋯N and C-H⋯F inter-actions are also observed.
In the title compound, C(15)H(12)FN(3)O(3)S(2), the two six-membered rings are essentially coplanar, their mean plnes making a dihedral angle of 1.1 (2)°. The carbonyl C, the two attached non-fused C atoms and the S atom deviate from the plane of the benzene ring by -0.046 (5), -0.017 (5), 0.000 (6), 0.026 (4) Å, respectively. The angle between the mean(More)
In the title compound, C(10)H(8)FN(3)O·0.5H(2)O, the dihedral angle between the mean planes of the rings is 99.80 (4)°. The water mol-ecule lies on a twofold axis. Weak inter-molecular O-H⋯N and C-H⋯O hydrogen bonds link one water mol-ecule with four phenyl-ethanone mol-ecules, while inter-molecular C-H⋯O hydrogen bonds involving the ketone group link(More)
The asymmetric unit of the title compound, C(13)H(10)FN(3)OS(2), contains two independent mol-ecules, which differ slightly in the relative orientations of the triazole and ethyl-sulfanyl groups with respect to the planar thio-chromen-4-one frameworks. The dihedral angles between the mean planes of the triazole groups and the corresponding six-membered(More)
In the title compound, C(13)H(10)ClFO(3)S(2), the two-ring system is essentially planar, the mean plane of the benzene ring being inclined at 6.0 (2)° to the plane of the remaining four atoms. The ethyl-sulfanyl group is almost coplanar with the two rings [dihedral angle = 6.4 (2)°], while the carboxyl-ate group is almost perpendicular to it [dihedral angle(More)
The asymmetric unit of the title compound, C(14)H(10)FN(3)OS(2), contains two independent mol-ecules which differ in the relative orientations of the triazole and allyl-sulfanyl groups with respect to the planar thio-chromen-4-one frameworks. The N-N-C-C torsion angles are 128.2 (5) and -120.9 (5)°, while the C-S-C-S torsion angles are -17.4 (4) and 16.4(More)
