title: 1,4-Bis(1H-benzimidazol-1-yl)benzene.
abstract: In the title compound, C(20)H(14)N(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 mol-ecule. In the crystal, mol-ecules are linked by C-H⋯N inter-actions and weak aromatic π-π stacking [shortest centroid-centroid separation = 3.770 (2) Å] is observed.
