The title compound, C26H25N3, crystallizes with four independent molecules, 1–4, in the asymmetric unit of the triclinic unit cell. The allyl substituents on the imidazole rings adopt similar conformations in all four molecules. The imadazole and the 4-and 5-substituted phenyl rings of two pairs of molecules in the asymmetric unit stack parallel to (110). In contrast, the dimethylaniline systems in these pairs of molecules are almost normal to one another, with dihedral angles of 85.84 (10) and 85.65 (10)° between the benzene rings of the two dimethylaniline fragments of molecules 1 and 2, and 3 and 4, respectively. The crystal structure features an extensive series of C—H
π interactions that link the molecules into undulating rows along the c axis. The crystal studied was a pseudo-merohedral twin with twin law [-100, 0-10, 111] and the BASF parameter refined to 0.513 (3).

In the title compound, C19H16BrClO4, both the fused xanthene rings and one of the cyclohexane rings adopt envelope conformations, while the other cyclohexane ring is in a chair conformation. In the crystal, molecules are linked by C—HO hydrogen bonds, forming infinite chains running along [10-1] incorporating R22(16) ring motifs. In addition, C—Hπ interactions and weak π–π stacking interactions [centroid–centroid distance = 3.768 (3) Å] help to consolidate the packing.

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—Hπ 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].
