title: 2-Hy-droxy-ethanaminium 2-methyl-5-nitro-benzene-sulfonate.
abstract: In the crystal structure of the title salt, C(2)H(8)NO(+)·C(7)H(6)NO(5)S(-), the cations and anions are linked together by N-H⋯O and O-H⋯O hydrogen bonds, forming layers parallel to (100). The plane of nitro group is skew with respect to the plane of benzene ring, making a dihedral angle of 17.5 (2)°.
