Abstract
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—H⋯N hydrogen bond and three weak C—H⋯π interactions involving the fused benzene ring and the imidazole ring are observed, leading to a three-dimensional architecture.
Highlights
Cg2 is the centroid of the C4–C9 fused benzene ring and Cg1 is the centroid of the N1/C2/N3/C9/C8 imidazole ring
—H22···π interaction involving the imidazole ring and C23—H23···π interaction involving the fused benzene ring are found in the crystal structure (Fig. 2, Table 1)
Symmetry codes: (i) x+1/2, y−1/2, z; (ii) −x, y, −z+1/2; (iii) −x, −y+1, −z
