Bis[2-(2-hydroxy-3-methoxyphenyl)benzimidazolium] tetrachloridocuprate(II) methanol disolvate

Abstract

In the title compound, (C14H13N2O2)2[CuCl4]·2CH4O, the geometry of the CuC142− 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—H...O, N—H...Cl and O—H...Cl hydrogen bonds helps to consoldiate the structure. Aromatic π–π stacking interactions involving the benzimidazole ring system, with a centroid–centroid distance of 3.785 (3) Å, also occur.
