2-Trifluoro-methyl-1H-benzimidazol-3-ium hydrogen sulfate.
In the crystal of the title mol-ecular salt, C(8)H(6)F(3)N(2) (+)·HSO(4) (-), cation-to-anion N-H⋯O hydrogen bonds generate [100] chains. Anion-to-anion O-H⋯O hydrogen bonds generate [001] helices and cross-link the chains into a three-dimensional network.
