Abstract: The title compound, C₁₈H₁₆ClN₃O₄S, is a Schiff base ligand in which the H atom of the hydroxy group has moved to the N atom of the imine group, resulting in a zwitterion. The structure is stabilized by an intramolecular (N-HO) and five intermolecular (C-HO, C-HN and N-HO) hydrogen bonds. The molecules are linked to each other by hydrogen bonds and form a three-dimensional polymeric network. In addition, the aromatic rings are also involved in - interactions [centroid-centroid distance between aromatic rings = 3.7525 (11) Å].
