title: Redetermination of ethyl-ene-diammonium bis-(p-methyl-benzene-sulfonate) monohydrate.
abstract: In the asymmetric unit of the title compound, C(2)H(10)N(2) (2+)·2C(7)H(7)O(3)S(-)·H(2)O, there are two independent 4-methyl-benzene-sulfonate anions, one ethyl-enediammonium cation and a water mol-ecule. 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). Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds hold the three components together, affording a layer structure extending parallel to the (001) plane.
