title: 1,4-Bis(1H-benzimidazol-1-yl)but-2-ene.
abstract: In the pseudo-centrosymmetric mol-ecule of the title compound, C(18)H(16)N(4), two benzimidazole fragments form the dihedral angles of 83.49 (7) and 79.37 (7)°, with the mean plane of the linking butene chain. No classical inter-molecular inter-actions are observed. The porous crystal packing exhibits voids of 85 Å(3).
