title: 2-(Benzothia-zol-2-yl-sulfanyl)-acetic acid.
abstract: In the title compound, C(9)H(7)NO(2)S(2), the benzine ring is essentially co-planar with the thia-zole ring, making a dihedral angle of 0.36 (7)°. In the crystal structure, mol-ecules are linked by inter-molecular O-H⋯N hydrogen bonds between the carb-oxy group and the thia-zole N atom into chains along [10]. The chains are assembled into a supermolecular layer structure by thia-zole ring S⋯S contacts [3.5679 (7) Å].
