(E)-4-[(2-Hydroxy-benzyl-idene)amino]benzene-sulfonic acid.

ABSTRACT: The title mol-ecule, C(13)H(11)NO(4)S, displays a trans configuration with respect to the imine C=N double bond. The central benzene ring directly linked to N and the hydroxyl group are disordered over two orientations [occupancies of 0.510?(16)/0.490?(16) and 0.528?(8)/0.472?(8), respectively]. The dihedral angle between the two aromatic rings is 23.3?(5)° for the major component and 18.3?(5)° for the minor component. There is an intra-molecular O-H?N hydrogen bond and mol-ecules are linked into chains along the a axis by O-H?O hydrogen bonds.
