Redetermination of ethylenediammonium bis(p-methylbenzenesulfonate) monohydrate

Abstract

In the asymmetric unit of the title compound, C2H10N22+·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.
