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].
在标题化合物C₉H₇NO₂S₂中,苯环与噻唑环基本共平面,二面角为0.36 (7)°。在晶体结构中,分子通过羧基与噻唑N原子之间的分子间O—H⋯N氢键沿[10]方向连接成链。这些链通过噻唑环的S⋯S接触[3.5679 (7) Å]组装成超分子层结构。
