ABSTRACT
The title Schiff base, C14H11NO3, crystallizes as a zwitterion (i.e. proton transfer from the carb-oxy-lic acid group to the imine N atom). The dihedral angle between the aromatic rings is 19.59â
(6)° and an intra-molecular N-Hâ¯O hydrogen bond closes an S(6) ring. In the crystal, inversion dimers linked by pairs of O-Hâ¯O hydrogen bonds generate R 2 (4)(24) loops. The dimers are linked by C-Hâ¯O inter-actions, generating (211) sheets.
