In the title compound, C6H6N2O3·C8H8O4, the 2-amino-4-nitrophenol (ANP) and 1-(2,4,6-trihydroxyphenyl)ethanone (THA) molecules are both nearly planar, with r.m.s. deviations of 0.0630 and 0.0313 Å, respectively. The angle between the least-squares planes of THA and ANP is 48.99 (2)°. In THA, an intramolecular O—HO hydrogen bond generates an S(6) ring motif. In the crystal, N—HO, O—HO and O—HN hydrogen bonds lead to the formation of a three-dimensional network. There are also intermolecular π–π interactions between the benzene rings of ANP–ANP and of THA–THA molecules, with centroid–centroid distances of 3.5313 (14) and 3.8440 (16) Å, respectively. Weak C—Oπ and N—Oπ interactions also occur.

The title Schiff base, C17H19IN2O, is not planar, displaying a dihedral angle of 34.9 (2)° between the two aromatic rings. The molecular conformation allows the formation of a strong intramolecular O—HN hydrogen bond with graph-set motif S(6) between the hydroxy group and the imine N atom.

The title compound, C23H16N2OS, is not planar, the phenyl ring of the benzoyl group making a dihedral of 77.61 (7)° with the benzothiophene system ring. The benzothiophene system and the remaining phenyl ring make an angle of 12.71 (13)°. The conformation around the imine functions is E for the C=N bond towards the benzothiophene system and Z for the C=N bond towards the benzoyl group. The packing of the molecules shows C—Hπ interactions. A weak intramolecular C—HN bond also occurs.

In the title Schiff-base type compound, C18H13N3O5, the central furan ring makes dihedral angles of 12.80 (7) and 51.43 (4)° with the terminal benzene rings. The dihedral angle between the benzene rings is 45.43 (3)°. In the crystal, C—HO hydrogen bonds link the molecules into layers parallel to (010). In addition, there are π–π stacking interactions within the layer [centroid–centroid distance = 3.584 (1) Å] and between the layers [centroid–centroid distance 3.751 (1) Å].

In the title compound, C12H10N2O3S, the dihedral angle between the benzene and thiophene rings is 43.17 (4)°. The crystal structure is devoid of any hydrogen-bonding interactions. However, π–π interactions between the benzene and thiophene rings [distance between ring centroids = 3.6850 (11) Å] stack the molecules along the a axis. The absolute structure could not be determined as the crystal studied was a racemic twin with a BASF parameter of 0.31 (6).
