Abstract: In the title compound, (C₁₄H₁₃N₂O₂)₂[CuCl₄]·2CH₄O, the geometry of the CuC1₄^2- ions (Cu site symmetry 2) is intermediate between tetrahedral and square-planar. The dihedral angle between the benzimidazole and benzene ring systems is 8.74(14)°. A network of N-HO, N-HCl and O-HCl hydrogen bonds helps to consoldiate the structure. Aromatic - stacking interactions involving the benzimidazole ring system, with a centroid-centroid distance of 3.785 (3) Å, also occur.
