✦ Synopsis
In the crystal structure of the title compound, C 11 H 10 N 3 O 4 S + Á-Cl À Á0.5H 2 O, there are two formula units in the asymmetric unit. A network of N-HÁ Á ÁCl, N-HÁ Á ÁO and O-HÁ Á ÁCl hydrogen bonds helps to establish the crystal packing. The nitro group of one of the organic cations is disordered over two positions in a 0.57 (2):0.43 (2) ratio.
