(2Z)-3-(2,4-Di-chloro-phen-yl)-3-hy-droxy-N-phenyl-prop-2-ene-thio-amide.

In the title mol-ecule, C15H11Cl2NOS, the dihedral angle between the phenyl and benzene rings is 72.24 (1)°. In the crystal, pairs of N-H⋯S hydrogen bonds form dimers with twofold rotational symmetry. The dimers are connected by weak C-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (001). An intra-molecular O-H⋯S hydrogen bond is also observed.

3-Methyl-4-{(E)-[4-(methyl-sulfan-yl)benzyl-idene]amino}-1H-1,2,4-triazole-5(4H)-thione.

In the title mol-ecule, C11H12N4S2, the dihedral angle between the triazole and benzene rings is 21.31 (5)°. A weak intra-molecular C-H⋯S hydrogen bond generates an S(6) ring motif. In the crystal, pairs of N-H⋯S hydrogen bonds form inversion dimers. In addition, π-π inter-actions are observed between the benzene rings, with a centroid-centroid separation of 3.7599 (11) Å.

4-Amino-3-(3-meth-oxy-benz-yl)-1H-1,2,4-triazole-5(4H)-thione.

In the title mol-ecule, C10H12N4SO, the triazole ring forms a dihedral angle of 73.0 (5)° with the benzene ring. The meth-oxy group is approximtely coplanar with the benzene ring with a C C-O-Cmeth-yl torsion angle of 4.7 (3)°. In the crystal, N-H⋯S hydrogen bonds connect pairs of inversion-related mol-ecules, which are in turn connected by N-H⋯N hydrogen bonds into chains of rings along [010]. Weak C-H⋯O hydrogen bonds connect these chains into a two-dimensional network parallel to (-102).

(7-Chloro-2-oxo-2H-chromen-4-yl)methyl piperidine-1-carbodithio-ate.

In the title compound, C(16)H(16)ClNO(2)S(2), the piperidine ring is in a chair conformation. In the coumarin ring system, the dihedral angle between the benzene and pyran rings is 3.5 (1)°. In the crystal, a weak C-H⋯O hydrogen bond links mol-ecules into chains along [001]. In addition, π-π stacking inter-actions are present involving the benzene and pyran rings, with a centroid-to-centroid distance of 3.712 (2) Å. The crystal studied is a nonmerohedral twin with refined components 0.221 (1) and 0.779 (1).
