In the mol-ecule of the title compound, C(10)H(9)NO(6)S·H(2)O, the benzothia-zine ring adopts an envelope conformation. An intra-molecular N-H⋯O hydrogen bond results in the formation of a nonplanar five-membered ring which has a twisted conformation. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules to form a three-dimensional network. There is a π-π contact between the benzene rings [centroid-centroid distance = 3.972 (2) Å].
在标题化合物C(10)H(9)NO(6)S·H(2)O的分子中，苯并噻嗪环呈信封构象。分子内N-H⋯O氢键导致形成一个具有扭曲构象的非平面五元环。在晶体结构中，分子间的N-H⋯O、O-H⋯O和C-H⋯O氢键将分子连接形成三维网络。苯环之间存在π-π接触[质心-质心距离 = 3.972 (2) Å]。
