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.
