In the title molecule, C18H17N5O3S2, the heterocyclic thiazine ring adopts a twist boat conformation, with the S and N atoms displaced by 0.480 (7) and 0.205 (8) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The pyrazole and benzene rings are tilted at an angle of 10.9 (2)° with respect to one another. The crystal structure is stabilized by intermolecular N—HO and C—HN hydrogen bonds, resulting in dimers forming nine-membered rings of graph-set motif R22(9). In addition, intermolecular C—HO interactions result in chains of molecules along the c axis, further consolidating the crystal packing.

In the title molecule, C8H9NS, the mean plane of the carbothioamide group is twisted slightly with respect to the mean plane of the benzene ring, making a dihedral angle of 17.03 (10)°. The crystal structure is stabilized by intermolecular N—HS hydrogen bonds, resulting in the formation of eight-membered rings lying about inversion centers and representing R22(8) and R42(8) motifs. Futhermore, these hydrogen bonds build up chains parallel to the b axis.

The asymmetric unit of the title compound, C8H9NOS, contains two independent molecules with the methoxy groups oriented in opposite conformations. The mean planes of the carbothioamide groups are tilted by 7.88 (15) and 11.16 (9)° from the mean planes of the benzene rings. In the crystal, the molecules form dimers via intermolecular N—HS intermolecular hydrogen bonds, resulting in eight-membered rings of R22(8) graph-set motif. The dimers are further linked by C—HO hydrogen bonds into chains along the c axis. Adjacent chains interact through intermolecular N—HS hydrogen bonds, generating eight-membered rings of R42(8) graph-set motif.

The title molecule, C16H13ClO2, is trans with respect to the C=C double bond. The dihedral angles between the mean plane of the prop-2-en-1-one unit and those of the 3-chloro- and 4-methoxy-substituted benzene rings are 20.93 (9) and 20.42 (10)°, respectively, and the dihedral angle between the mean planes of the two benzene rings is 40.96 (5)°. The crystal structure is stabilized by weak intermolecular C—HO hydrogen bonds, forming chains along the b axis.
