title: 2-Methyl-1H-benzimidazol-3-ium hydrogen phthalate.
abstract: The asymmetric unit of the title compound, C(8)H(9)N(2) (+)·C(8)H(5)O(4) (-), contains two independent ion pairs. In each 2-methyl-1H-benzimidazolium ion, an intra-molecular O-H⋯O bond forms an S(7) graph-set motif. In the crystal, the components are linked by N-H⋯O hydrogen bonds, forming chains along [210]. Further stabilization is provided by weak C-H⋯O hydrogen bonds.
