In the title compound, C18H17FN2O, the imidazole ring makes dihedral angles of 68.81 (6) and 25.20 (8)° with the methoxyphenyl and fluorophenyl rings, respectively. The dihedral angle between the methoxyphenyl and fluorophenyl ring is 71.89 (6)°. In the crystal, molecules are linked into inversion dimers with an R22(8) graph-set motif by pairs of weak C—H
F interactions.

In the title compound, C23H16N2·0.5C6H6, the benzimidazole unit [maximum deviation = 0.0258 (6) Å] and the naphthalene ring system [maximum deviation = 0.0254 (6) Å] are both essentially planar and make a dihedral angle of 61.955 (17)°. The imidazole ring makes dihedral angle of 61.73 (4)° with the phenyl ring. An intramolecular C—HN hydrogen bond generates an S(6) ring motif. In the crystal, seven weak C—Hπ interactions involving the fused ring system, the benzene solvent molecule, the imidazole phenyl rings are observed, leading to a three-dimensional architecture.

The title molecule, C13H10N2O, is essentially planar, the maximum deviation from the plane of the non-H atoms being 0.016 (2) Å. The imidazole ring makes a dihedral angle of 0.37 (13)° with the attached benzene ring. An intramolecular O—HN hydrogen bond generates an S(6) ring motif. In the crystal, molecules are linked through N—HO hydrogen bonds, forming chains propagating in [001]. The crystal packing also features four π–π stacking interactions involving the imidazole ring, fused benzene ring and attached benzene ring system [centroid–centroid distances = 3.6106 (17), 3.6108 (17), 3.6666 (17) and 3.6668 (17) Å].

In the title compound, C23H24F2O3, the central pyran ring has a flat-boat conformation, whereas the two fused cyclohexenone rings adopt envelope conformations, with the C atom bearing the dimethyl substituent being the flap atom in each case. The pyran ring mean plane and the difluorophenyl ring are almost normal to each other, making a dihedral angle of 87.55 (4)°. In the crystal, molecules are linked by pairs of C—HO hydrogen bonds, forming inversion dimers with an R22(8) ring motif. The F atom at position 2 on the difluorophenyl ring is disordered over the 2- and 6-positions, and has a refined occupancy ratio of 0.932 (3):0.068 (3).
