The title compound, C27H28N2O, is a lophine (2,4,5-triphenyl-1H-imidazole) derivative with an n-pentyl chain on the amine N atom and a 4-methoxy substituent on the benzene ring. The two phenyl and methoxybenzene rings are inclined to the imidazole ring at angles of 25.32 (7), 76.79 (5) and 35.42 (7)°, respectively, while the methoxy substituent lies close to the plane of its benzene ring, with a maximum deviation of 0.126 (3) Å for the methoxy C atom. In the crystal, inversion dimers linked by pairs of C—HO hydrogen bonds generate R22(22) loops. These dimers are stacked along the a-axis direction.

In the title compound, C19H17NO2, the dihedral angle between the benzene ring and the naphthalene ring system is 9.72 (5)°, while the torsion angle of the C—N—C—C bridging group is 179.24 (17)°. The methyl group of the 1-phenylethanol moiety is disordered over two positions with a refined occupancy ratio of 0.775 (5):0.225 (5). The molecular conformation is stabilized by an intramolecular N—HO hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked by O—HO hydrogen bonds, forming zigzag chains propagating along the c-axis direction. Neighbouring chains are linked via C—HO interactions, forming a two-dimensional slab-like network parallel to the bc plane.

The molecular conformation of the title compound, C13H8BrFN2O3, is essentially planar, with maximum deviations of 0.076 (1) and −0.080 (2) Å for the O atoms of the NO2 group. The molecular conformation is stabilized by an intramolecular O—HN hydrogen bond, forming an S(6) ring motif. In the crystal, pairs of molecules are linked via two pairs of C—HO hydrogen bonds, forming inversion dimers that enclose R22(7)R22(10)R22(7) ring motifs.
