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-mol­ecules, each located on an inversion centre, and a methanol solvent mol­ecule. 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 mol­ecules. In the crystal, a two-dimensional network is formed through N—H⋯ N, N—H⋯O and O—H⋯N hydrogen-bonding inter­actions between the benzimidazole units and methanol solvent mol­ecules. π–π stacking inter­actions also occur between the benzimidazole rings of adjacent mol­ecules, with centroid–centroid distances of 3.720 (14) Å and inter­planar distances of 3.53 (1) Å .
