title: 7-Benzenesulfonamido-3-methyl-8-oxo-5-thia-1-azabicyclo[4.2.0]octa-2-ene-2-carboxylic acid monohydrate.
abstract: In the title compound, C(14)H(14)N(2)O(5)S(2)·H(2)O, the six-membered ring fused to the β-lactam unit has a twisted conformation. Weak intra-molecular N-H⋯S and C-H⋯O inter-actions occur. Inter-molecular C-H⋯S, N-H⋯O, C-H⋯O and O-H⋯O hydrogen-bonding inter-actions stabilize the crystal structure, forming a three-dimensional network. Weak C-H⋯π inter-actions are also present.
