title: 7-Benzene-sulfonamido-3-ethenyl-8-oxo-5-thia-1-aza-bicyclo-[4.2.0]oct-2-ene-2-carboxylic acid methanol solvate.
abstract: In the title compound, C(15)H(14)N(2)O(5)S(2)·CH(4)O, the six-membered ring fused to the β-lactam unit adopts a twisted conformation. In the crystal structure, the component mol-ecules are linked into a three-dimensional framework through inter-molecular N-H⋯S, N-H⋯O and O-H⋯O hydrogen bonds and C-H⋯O contacts.
