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 = 0.0254 (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 intra-molecular C-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, seven weak C-H⋯π inter-actions involving the fused ring system, the benzene solvent mol-ecule, the imidazole phenyl rings are observed, leading to a three-dimensional architecture.
