In the title compound, C13H11ClN4O3, the phenyl and pyrrolyl ring are linked by an acyl–hydrazone (R2C=N—N—CO—R) group, forming a slightly bent molecule: the dihedral angle subtended by the the phenyl and pyrrolyl rings is 8.46 (12)°. In the crystal, the three-dimensional supramolecular structure is assembled by N—H
O hydrogen bonding. Molecular sheets are formed parallel to (101) in a herringbone arrangement by weak van der Waals interactions; weak π–π [centroid–centroid phenyl–phenyl and pyrrolyl–pyrrolyl distances of 3.7816 (3) and 3.8946 (2) Å, respectively] interactions occur between neighbouring sheets.

In the title compound, C13H12N4O3, the dihedral angle between the planes of the pyrrole and benzene rings is 7.47 (1)°. In the crystal, molecules are arranged in sheets lying parallel to (101). Neighbouring sheets are linked by N—HO hydrogen bonds, weak π–π [centroid–centroid distance between the pyrrole rings = 3.765 (11) Å] and C—Hπ interactions, forming a three-dimensional structure.

In the title compound, C9H9N3OS, the plane of the benzene ring forms a dihedral angle of 33.40 (5)° with that of the triazole group. In the crystal, molecules are linked by O—HN hydrogen bonds involving the phenol –OH group and one of the unsubstituted N atoms of the triazole ring, resulting in chains along [010]. These chains are further extended into a layer parallel to (001) by weak C—HN hydrogen-bond interactions. Aromatic π–π stacking [centroid–centroid separation = 3.556 (1) Å] between the triazole rings links the layers into a three-dimensional network.
