In the title compound, C24H22N2O2, the central imidazole ring makes dihedral angles of 49.45 (8), 88.94 (9) and 19.43 (8)° with the benzene ring and the two phenyl rings, respectively. The dihedral angle between the phenyl rings is 77.86 (9)°, and they form dihedral angles of 49.06 (9) and 67.31 (8)° with the benzene ring. In the crystal, molecules are linked by O—H
N hydrogen bonds, forming chains along the b axis. These chains are connected by C—HO hydrogen bonds, forming a two-dimensional network parallel to (100). In addition, C—Hπ interactions are also observed. The terminal C and O atoms of the ethanol group are disordered over two sets of sites with an occupancy ratio of 0.801 (5):0.199 (5).

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—Hπ 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 xanthene ring system in the title compound, C19H18O4, the 4H-pyran ring has a maximum deviation of 0.110 (2) Å from planarity and the cyclohexene ring exhibits a puckered conformation [puckering parameters QT = 0.452 (3) Å, θ = 57.0 (4) and φ = 131.7 (4)°]. The cyclohexene ring attached to the xanthene system adopts an envelope conformation, with the middle of the three methylene C atoms as the flap atom. In the crystal, O—HO and C—HO hydrogen bonds form infinite chains of R12(6) ring motifs along [100] with the xanthene groups arranged in an alternating zigzag manner.
