The crystal structure of ethylenediammonium bis (p-methylbenzenesulfonate) monohydrate, $C_2H_{10}N_{22}^{+2}{\cdot}(C_7O_3H_7S^-){\cdot}H_2O$ has been determined by X-ray diffraction techniques. The space group is P21, in 2 unit cell with a = 12.649 (2) ${\AA}$, b = 7.727 (1) ${\AA}$, c = 11.295 (2) ${\AA}$, ${\beta}$ =111.8(1)$^{\circ}$, and z = 2. The structure was solved by direct methods and refined to R = 0.060 for 1134 reflections measured with Mo-K${\alpha}$ radiation. Two p-methylbenzenesulfonates, fragment A and B, from a pair through the hydrogen bonds to the ethylenediammonium ion. The sulfonate group in the fragment B are disordered. There are six unique hydrogen bonds, of which four are between the ethylenediammonium ion and the sulfonate groups and remaining two involve the water molecule
