Abstract:
In the crystal of the title mol-ecular salt {systematic name: bis-[2-(2-hy-droxy-phen-yl)-1H-benzimidazol-3-ium] 2,5-di-chloro-3,6-dioxo-cyclo-hexa-1,4-diene-1,4-diolate}, 2C13H11N2O+·C6Cl2O4 2-, the chloranilate anion is located on an inversion centre, so that the asymmetric unit contains one cation and one half of the chloranilate anion. In the crystal, the cation and the anion are connected by a bifurcated N-H⋯(O,O) hydrogen bond, forming a 2:1 unit. The units are linked into a layer lying parallel to (01) via O-H⋯O and N-H⋯Cl hydrogen bonds. Between the layers, a C-Cl⋯π inter-action is observed.
