title: 1,1'-(Butane-1,4-di-yl)bis-[2-(pyridin-2-yl)-1H-benzimidazole].
abstract: The complete mol-ecule of the title compound, C(28)H(24)N(6), is generated by inversion symmetry with the inversion centre located at the mid-point of the central C-C bond of the butanediyl unit. The benzimidazole and pyridine rings are almost coplanar, the dihedral angle between their mean planes being 6.86 (11)°.
