Abstract

The structure of 8-amino-2-naphthalene-sulfonic acid monohydrate (1,7-Cleve's acid hydrate), C(10)H(9)NO(3)S·H(2)O, shows the presence of a sulfonate-aminium group zwitterion, both groups and the water mol-ecule of solvation giving cyclic R(3) (3)(8) O-H⋯O and N-H⋯O inter-molecular hydrogen-bonding inter-actions, forming chains which extend down the a axis of the unit cell. Additional peripheral associations, including weak aromatic ring π-π inter-actions [centroid-centroid distance = 3.6299 (15) Å], result in a two-dimensional sheet structure.
