2-(4-Bromobenzenesulfonamido)acetic acid
نویسندگان
چکیده
The title compound, C(8)H(8)BrNO(4)S, a halogenated sulfon-amide, was prepared by basic hydrolysis of the methyl ester. In the crystal, mol-ecules form centrosymmetric hydrogen-bonded dimers via the carboxyl groups. These dimers are further linked by N-H⋯O inter-actions involving the carbonyl O and amide H atoms, forming a ribbon-like structure propagating in [010]. These ribbons are further linked via C-H⋯O inter-actions, forming a three-dimensional network.
