2-[(E)-(2,4-Dihy­droxy­benzyl­idene)aza­nium­yl]-3-phenyl­propano­ate

The title compound, C(16)H(15)NO(4), exists as a zwitterion in the solid state, with the carb­oxy­lic acid group being deprotonated and the imine N atom being protonated. The mol­ecule adopts an E configuration about the C=N double bond. The dihedral angle between the benzene rings is 46.34 (4)°. An...

Sumario:The title compound, C(16)H(15)NO(4), exists as a zwitterion in the solid state, with the carb­oxy­lic acid group being deprotonated and the imine N atom being protonated. The mol­ecule adopts an E configuration about the C=N double bond. The dihedral angle between the benzene rings is 46.34 (4)°. An intra­molecular N—H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, adjacent mol­ecules are connected by inter­molecular O—H⋯O and C—H⋯O hydrogen bonds, forming supra­molecular ribbons along the a axis.
