Crystal structure of (E)-2-[(4-hy­droxy­benzyl­idene)aza­nium­yl]benzoate

The title Schiff base, C(14)H(11)NO(3), crystallizes as a zwitterion (i.e. proton transfer from the carb­oxy­lic acid group to the imine N atom). The dihedral angle between the aromatic rings is 19.59 (6)° and an intra­molecular N—H⋯O hydrogen bond closes an S(6) ring. In the crystal, inversion dime...

description The title Schiff base, C(14)H(11)NO(3), crystallizes as a zwitterion (i.e. proton transfer from the carb­oxy­lic acid group to the imine N atom). The dihedral angle between the aromatic rings is 19.59 (6)° and an intra­molecular N—H⋯O hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O—H⋯O hydrogen bonds generate R (2) (4)(24) loops. The dimers are linked by C—H⋯O inter­actions, generating (211) sheets.
