2-(1H-Benzimidazol-2-yl)phenol.

The title mol-ecule, 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.

2-(Naphthalen-1-yl)-1-phenyl-1H-benzimid-azole benzene hemisolvate.

In the title compound, C23H16N2·0.5C6H6, the benzimidazole unit [maximum deviation = 0.0258 (6) Å] and the naphthalene ring system [maximum deviation = 0.

2-(1-Phenyl-1H-benzimidazol-2-yl)phenol.

In the title mol-ecule, C19H14N2O, the benzimidazole unit is close to being planar [maximum deviation = 0.0253 (11) Å] and forms dihedral angles of 68.98 (6) and 20.

1,2-Diphenyl-1H-benzimidazole.

In the title mol-ecule, 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.

2-(4-Fluoro-phen-yl)-1-(4-methyl-phen-yl)-1H-phenanthro[9,10-d]imidazole.

The phenanthrene tricyclic ring system in the title mol-ecule, C(28)H(19)FN(2), is slightly skewed with a dihedral angle of 7.50 (6)° between the outer benzene rings. The p-tolyl and fluoro-benzene rings are twisted from the attached imidazole ring by 70.
