8-Ammonio­naphthalene-2-sulfonate monohydrate: the zwitterionic hydrate of 1,7-Cleve’s acid

The structure of 8-amino-2-naphthalene­sulfonic 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 mol­ecule of solvation giving cyclic R (3) (3)(8) O—H⋯O and N—H⋯O inter­molecular hydrogen-bonding...

Sumario:The structure of 8-amino-2-naphthalene­sulfonic 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 mol­ecule of solvation giving cyclic R (3) (3)(8) O—H⋯O and N—H⋯O inter­molecular hydrogen-bonding inter­actions, forming chains which extend down the a axis of the unit cell. Additional peripheral associations, including weak aromatic ring π–π inter­actions [centroid–centroid distance = 3.6299 (15) Å], result in a two-dimensional sheet structure.
