4,4′-Bis(benzimidazol-1-yl)biphenyl

Abstract

The molecule of the title compound, C26H18N4, 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 interplanar separations of ca 3.4 Å complete the interactions.
