The title molecule, C9H7ClN4OS, is almost planar, with an r.m.s. deviation of 0.034 (2) Å for the mean plane through all the non-H atoms. Intramolecular N—HO and N—HN hydrogen bonds form S(6) and S(5) ring motifs, respectively. In the crystal, molecules are assembled into inversion dimers through pairs of co-operative N—HCl interactions. These dimers are connected along the b axis by N—HO and N—HS hydrogen bonds, generating layers parallel to (103). The layers are further connected along the a axis into a three-dimensional network, through weak π–π stacking interactions [centroid–centroid distance = 3.849 (2) Å].

In the title compound, C14H13ClN4S, obtained from a reaction of 2-benzoyl-4-chloroaniline with thiosemicarbazide in ethanol, the dihedral angle between the aromatic rings is 81.31 (13)°. In the crystal, the molecules are linked by three N—HS hydrogen bonds, forming centrosymmetric rings with set-graph motif R22(8) and R22(18), and resulting in the formation of a two-dimensional network lying parallel to (010).

In the title compound, C13H13ClO4, the dihedral angle between the chlorobenezene ring and the least-squares plane through the 4-methoxy-2-oxobut-3-enoate ethyl ester residue (r.m.s. deviation = 0.0975 Å) is 54.10 (5)°. In the crystal, molecules are connected by methoxy–ketone and benzene–carboxylate carbonyl C—HO interactions, generating a supramolecular layer in the ac plane.
