The title compound, C24H19ClN2, crystallizes with two independent molecules in the asymmetric unit. The prop-2-enyl substituents on the imidazole rings adopt similar conformations in the two molecules. The 4-and 5-substituted phenyl rings and the benzene ring make dihedral angles of 67.06 (8), 5.61 (8) and 41.09 (8)°, respectively, with the imadazole ring in one molecule and 71.53 (8), 28.85 (8) and 41.87 (8)°, respectively, in the other. The crystal structure features C—H
π interactions and weak π–π stacking interactions [centroid–centroid distances = 3.6937 (10) and 4.0232 (10) Å] between the chlorophenyl rings, which form a three-dimensional supramolecular structure.

In the title compound, C24H20N2, one of the ring C atoms and one of the ring N atoms are disordered over two sets of sites in a 0.615 (3):0.385 (3) ratio. The two parts of the disordered imidazole ring adopt an envelope conformation, with the undisordered ring N atom as the flap, displaced by −0.118 (6) and 0.226 (7) Å, respectively, in the two disorder components from the plane through the other ring atoms. The crystal structure features C—HN hydrogen bonds and C—Hπ interactions, which lead to the formation of infinite chains along [010].

In the title compound, C26H24N2O2, the two phenyl and the 2,5-dimethoxyphenyl rings are inclined to the imidazole ring at dihedral angles of 30.38 (8), 56.59 (9) and 73.11 (9)°, respectively. In the crystal, molecules are linked by pairs of C—HO interactions into centrosymmetric dimers with graph-set notation R22(8). C—Hπ interactions are also observed.

The title compound, C25H20N2O2, crystallized with two molecules in the asymmetric unit, in one of which the atoms of the terminal propenyl group are disordered over two sets of sites, with a refined occupancy ratio of 0.870 (4):0.130 (4). The central imidazole ring makes dihedral angles of 25.51 (11), 40.73 (11) and 27.36 (11)° with the three pendant rings in one molecule and 22.56 (10), 60.72 (10) and 5.85 (10)° in the other. In the crystal, molecules are linked by N—HN and C—HO hydrogen bonds, forming a three-dimensional network. The crystal structure also features C—Hπ interactions and π–π stacking [centroid–centroid distances = 3.8834 (18) and 3.9621 (17) Å] interactions.

In the title compound, C20H20N2O3, the central 2,5-dihydro-1H-pyrrole ring [r.m.s. deviation = 0.014 (1) Å] is oriented at dihedral angles of 77.81 (6) and 25.33 (6)°, respectively, to the attached phenyl ring and the aniline phenyl ring. An intramolecular N—HO hydrogen bond occurs. In the crystal, molecules are linked through pairs of N—HO hydrogen bonds, forming inversion dimers with an R22(10) ring motif. Two weak C—Hπ interactions are also observed.

In the title compound, C20H18Cl2N2O3, the dihedral angles between the central 2,5-dihydro-1H-pyrrole ring and the phenyl rings are 74.87 (9) and 29.09 (9)°. Intramolecular N—HO and C—HO hydrogen bonds occur. In the crystal, pairs of N—HO hydrogen bonds link adjacent molecules into inversion dimers and form an R12(6)R22(10)R12(6) ring motif through C—HO hydrogen bonds.
