1,4-Bis(1H-benzimidazol-2-yl)benzene methanol monosolvate.

The asymmetric unit of the title compound, C(20)H(14)N(4)·CH(4)O, contains two independent half-mol-ecules, each located on an inversion centre, and a methanol solvent mol-ecule. The benzimidazolyl groups form different dihedral angles [24.0 (1) and 11.6 (1)°] with the plane of the central benzene ring in the two mol-ecules. In the crystal, a two-dimensional network is formed through N-H⋯ N, N-H⋯O and O-H⋯N hydrogen-bonding inter-actions between the benzimidazole units and methanol solvent mol-ecules. π-π stacking inter-actions also occur between the benzimidazole rings of adjacent mol-ecules, with centroid-centroid distances of 3.720 (14) Å and inter-planar distances of 3.53 (1) Å .
