title: 2-[(E)-2-(4-Methyl-benzene-sulfonamido)ethyl-iminiometh-yl]-4-nitro-phenolate.
abstract: The mol-ecule of the title compound, C(16)H(17)N(3)O(5)S, crystallizes in a zwitterionic form, with a strong intra-molecular N-H⋯O hydrogen bond. The dihedral angle between the two benzene rings is 7.06 (9)°. In the crystal, mol-ecules are linked into chains along the c axis by inter-molecular N-H⋯O hydrogen bonds.
