In the title compound, C19H14FNS2, the seven-membered thiazepine ring adopts a slightly distorted twist boat conformation. The dihedral angle between the benzene rings is 53.6 (1)°. The mean plane of the thiazepine ring is twisted by 34.3 (7)° and 36.6 (7)° from the benezene rings. A C—HF interaction generates stacking of molecules along the ab plane.

In the title compound, C13H13NO3, the conformation across the C=C bond is synperiplanar, the torsion angle of the segment C(ring)—C=C—C(N) being 3.2 (5)°. In the crystal, molecules are linked into inversion dimers, arranged in a zigzag pattern, through two C—HO interactions generating R22(10) and R22(14) motifs. These dimers are arranged in a zigzag pattern in the crystal structure. The molecules are further linked along the c axis through weak C—Hπ interactions, and weak ππ interactions [centroid–centroid separation = 3.9986 (17) Å] are also observed.

The asymmetric unit of the title compound, C11H10N4O3, contains two independent molecules in which the benzene rings make dihedral angles of 38.3 (2) and 87.1 (2)° with respect to the triazole rings. In the crystal, the molecules are linked by C—HO hydrogen bonds, forming chains along [021]. Further, weak C—Oπ [3.865 (5) Å, 83.8 (3)°] and N—Oπ [3.275 (5) and 3.240 (6) Å, 141.8 (4) and 102.8 (3)°] interactions are observed.
