In the title compound, C22H19NO2S, the cyclohexene ring adopts a slightly distorted half-chair conformation. The dihedral angles between the mean planes of the thiophene ring and the phenyl and 2-hydroxyphenyl rings are 70.4 (5) and 12.1 (9)°, respectively. The phenyl and 2-hydroxyphenyl rings are twisted with respect to one another by 81.0 (6)°. A short intramolecular O—HN hydrogen bond is observed. In the crystal, weak C—HO interactions link the molecules into zigzag chains diagonally along [100] .

The title compound, C24H20N2OS, crystallizes with two independent molecules (A and B) in the asymmetric unit, in each of which the cyclohexene rings adopt half-chair conformations. The mean plane of the indole ring is twisted from those of the phenyl and thiophene rings by 69.0 (7) and 8.3 (5)°, respectively, in molecule A and by 65.4 (9) and 6.7 (5)°, respectively, in molecule B. The dihedral angles between the mean planes of the phenyl and thiophene rings are 63.0 (4) and 58.8 (9)° in molecules A and B, respectively. In the crystal, N—HO hydrogen bonds lead to the formation of an infinite chain along [101]. In addition, π–π stacking interactions are observed involving the thiophene and pyrrole rings of the two molecules, with a shortest intercentroid distance of 3.468 (2) Å.

In the title compound, C22H19NOS, the cyclohexene ring of the tetrahydrobenzothiophenyl ring system adopts a slightly distorted half-chair conformation and is twisted slightly [7.5 (8)° for the major disorder component] from the mean plane of the thiophene ring. The dihedral angles between the mean planes of the thiophene ring and the phenyl rings are 65.7 (3) and 8.3 (4)°. The phenyl rings are twisted with respect to each other by 73.8 (7)°. Disorder was modeled for four C atoms of the cyclohexene ring over two sets of sites with an occupancy ratio of 0.659 (2):0.341 (2). In the crystal, a single weak C—HO interaction links the molecules into [001] chains.

In the title compound, C23H20BrNO2S, disorder was modeled for the outer two C atoms of the cyclohexene ring over two sets of sites with an occupancy ratio of 0.580 (11):0.420 (11). Both rings have a half-chair conformation. The dihedral angles between the mean plane of the thiophene ring and the benzene and phenyl rings are 9.2 (2) and 66.1 (2)°, respectively. The benzene and phenyl rings are inclined to each other by 74.8 (8)°. In the crystal, molecules are linked by pairs of C—HO hydrogen bonds, forming inversion dimers.

In the title compound, C19H18N4O4, the nitrophenyl and phenyl rings are twisted by 67.0 (6) and 37.4 (4)°, respectively, with respect to the pyrazole ring plane [maximum deviation = 0.0042 (16) Å]. The dihedral angle between the mean planes of the phenyl rings is 59.3 (3)°. The amide group, with a C—N—C—C torsion angle of 177.54 (13)°, is twisted away from the plane of the pyrazole ring in an antiperiplanar conformation. In the crystal, N—HO hydrogen bonds involving the carbonyl group on the pyrazole ring and the amide group, together with weak C—HO interactions forming R22(10) graph-set motifs, link the molecules into chains along [100]. Additional weak C—HO interactions involving the nitrophenyl rings further link the molecules along [001], also forming R22(10) graph-set motifs, thereby generating (010) layers.

In the title compound, C22H18N2O3S, disorder is found in the benzoyl group (A and B), as well as for four C atoms of the cyclohexene ring. Two orientations were modeled in a 0.583 (5):0.417 (5) ratio. The cyclohexene ring is in a distorted chair conformation. The dihedral angles between the mean plane of the thiophene ring and the 4-nitrobenzene and phenyl rings are 30.9 (8) and 64.8 (3) (A) and 62.4 (7)° (B). The mean planes of the 4-nitrobenzene and the phenyl rings are almost perpendicular to each other, with dihedral angles of 85.4 (1) (A) and 83.9 (8)° (B). An extensive array of weak C—HO interactions consolidate molecules into a three-dimensional architecture, forming chains along [001] and [010] and layers parallel to (011).
