2-[(2-Hydroxy-4-methoxybenzylidene)azaniumyl]benzoate monohydrate

Abstract

In the title compound, C15H13NO4·H2O, the Schiff base exists in a zwitterionic form and a bifurcated intramolecular N—H...(O,O) hydrogen bond generates two S(6) rings. The dihedral angle between the two benzene rings is 25.8 (2)°. The crystal structure is stabilized by intermolecular O—H...O hydrogen bonds.
