In the asymmetric unit of the title compound, C2H10N2
2+·2C7H7O3S−·H2O, there are two independent 4-methyl­benzene­sulfonate anions, one ethyl­enediammonium cation and a water mol­ecule. The present redetermination was carried out to improve the treatment of disorder, which was not refined in the previous study [Ahn & Kim (1985 ▶). J. Korean Chem. Soc.
29, 335–340]. One of the sulfonate groups is disordered over two positions, with site-occupancy factors of 0.588 (14) and 0.412 (14). Inter­molecular N—H⋯O and O—H⋯O hydrogen bonds hold the three components together, affording a layer structure extending parallel to the (001) plane.

    ABSTRACT: In the title salt, C2H10N2 2+·2C14H10NO3 −, the ethyl­ene­diaminium dication lies on an inversion centre. In the anion, the benzene rings make a dihedral angle of 33.87 (9)° and intramolecular N—H⋯O and C—H⋯O hydrogen bonds occur. All the amino H atoms are involved in N—H⋯O hydrogen bonds. These hydrogen bonds link the ionic units into a three-dimensional network. In addition, the crystal structure also features weak C—H⋯O inter­actions.
