title: 4,4'-Bis(benzimidazol-1-yl)biphen-yl.
abstract: The mol-ecule of the title compound, C(26)H(18)N(4), resides on a crystallographic inversion centre with a dihedral angle of 44.94 (5)° between the benzimidazole ring system and the benzene ring. The primary hydrogen bond is C-H⋯N and inversion-related pairs of these generate a chain of rings along the c-axis direction; π⋯π stacking involving the benzimidazole groups with inter-planar separations of ca 3.4 Å complete the inter-actions.
