1,4-Bis(1H-benzimidazol-1-yl)benzene

Abstract

In the title compound, C 20H 14N 4, the dihedral angles between the central benzene ring and the pendant benzimidazole ring systems are 46.60 (15) and 47.89 (16)°. The dihedral angle between the benzimidazole ring systems is 85.62 (12)° and the N atoms lie to the same side of the molecule. In the crystal, molecules are linked by C - H⋯N interactions and weak aromatic π-π stacking [shortest centroidcentroid separation = 3.770 (2) Å] is observed.
