Anilinium 3,4-dihy­droxy­benzoate

摘要

The asymmetric unit of the title salt, C6H8N⁺·C7H5O4 ⁻, contains two anilinium cations and two 3,4-dihy­droxy­benzoate anions. An intra­moleculer O—H⋯O hydrogen bond occurs in each anion. In the crystal, O—H⋯O and N—H⋯O hydrogen bonds link the cations and anions into a three-dimensional array. The structure is further consolidated by weak C—H⋯O inter­actions.
