2-[(2-Aza­niumyleth­yl)carbamo­yl]phenolate–phenol (1/1)

In the title 1:1 adduct, C₉H₁₂N₂O₂·C₆H₆O, the dihedral angle between the benzene ring and the salicylic amide group is 6.68 (6)°. The conformation of the amide group is supported by two intra­molecular N—H...O hydrogen bonds, which close S(6) and S(7) rings. In the crystal, the components are linked by O—H...O and N—H...O hydrogen bonds, generating (100) sheets.
