In the title compound, C19H19FN2O2, the imidazole ring is essentially planar [maximum deviation = 0.0030 (8) Å] and makes dihedral angles of 66.45 (7) and 29.98 (7)° with the benzene rings attached to the ring N and C atoms, respectively. The dihedral angle between the two benzene rings is 64.79 (7)°. A C—H
π interaction is found in the crystal structure. The two methoxy groups were found to be disordered over two sets of sites with occupancy factors of 0.803 (4) and 0.197 (4). The F atom is disordered over two sites with occupancy factors of 0.929 (4) and 0.071 (4).

In the title molecule, C19H13FN2, the benzimidazole unit is close to planar [maximum deviation = 0.0342 (9) Å] and forms dihedral angles of 58.94 (3) and 51.43 (3)° with the phenyl and fluorobenzene rings, respectively; the dihedral angle between the phenyl and fluorobenzene rings is 60.17 (6)°. In the crystal, three C—HF hydrogen bonds and two weak C—Hπ interactions involving the fused benzene ring lead to a three-dimensional architecture.

The phenanthrene tricyclic ring system in the title molecule, C28H19FN2, is slightly skewed with a dihedral angle of 7.50 (6)° between the outer benzene rings. The p-tolyl and fluorobenzene rings are twisted from the attached imidazole ring by 70.40 (7) and 28.33 (7)°, respectively. In the crystal, C—HF hydrogen bonds link the molecules into zigzag chains in [001], and weak C—Hπ interactions further consolidate the crystal packing.

In the title molecule, C19H14N2, the benzimidazole unit is close to being planar [maximum deviation = 0.0102 (6) Å] and forms dihedral angles of 55.80 (2) and 40.67 (3)° with the adjacent phenyl rings; the dihedral angle between the phenyl rings is 62.37 (3)°. In the crystal, one C—HN hydrogen bond and three weak C—Hπ interactions involving the fused benzene ring and the imidazole ring are observed, leading to a three-dimensional architecture.
N hydrogen bond and three weak C—Hπ interactions involving the fused benzene ring and the imidazole ring are observed, leading to a three-dimensional architecture.
