1H-Benzimidazol-3-ium-2-carboxyl­ate dihydrate

The title compound, C(8)H(6)N(2)O(2)·2H(2)O, crystallized as a zwitterion with the carboxyl group deprotonated and the imidazole group protonated. The dihedral angle between the benzimidazole ring and the pendant –CO(2) group is 0.62 (2)°. In the crystal, mol­ecules are linked into a three-dimension...

Sumario:The title compound, C(8)H(6)N(2)O(2)·2H(2)O, crystallized as a zwitterion with the carboxyl group deprotonated and the imidazole group protonated. The dihedral angle between the benzimidazole ring and the pendant –CO(2) group is 0.62 (2)°. In the crystal, mol­ecules are linked into a three-dimensional network by N—H⋯O and O—H⋯O hydrogen bonds.
