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.

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.
