biostudies-literatureUnknown67(Pt 10)Lin FThe 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.Acta crystallographica.
