Acta Crystallographica Section E Structure Reports Online (Impact Factor: 0.35). 01/2007; 64(Pt 1):o346. DOI: 10.1107/S1600536807066573

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.
