2-(Naphthalen-1-yl)-1-phenyl-1H-benzimidazole benzene hemisolvate

Abstract

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.
