2-(Naphthalen-1-yl)-1-phenyl-1H-benzimid­azole 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 intra­molecular C—H...N hydrogen bond generates an S(6) ring motif. In the crystal, seven weak C—H...π inter­actions involving the fused ring system, the benzene solvent mol­ecule, the imidazole phenyl rings are observed, leading to a three-dimensional architecture.
