In the title salt, C(15)H(17)N(4)O(4)S(2) (+)·Cl(-), the chloride anion is disordered over two positions with occupancies of 0.776 (6) and 0.224 (6). The cation adopts an L shape and the dihedral angle between the benzene rings is 82.5 (3)°. In the crystal, inversion dimers of cations linked by pairs of N-H⋯N hydrogen bonds occur, with the bond arising from the protonated N atom. The cationic dimers are linked into chains via the disordered chloride ions by way of N-H⋯Cl hydrogen bonds and N-H⋯O, C-H⋯O and C-H⋯Cl inter-actions also occur, which help to consolidate the three-dimensional network.
在标题盐C(15)H(17)N(4)O(4)S(2)(+)·Cl(-)中，氯离子阴离子在两个位置上无序分布，占有率分别为0.776 (6)和0.224 (6)。阳离子呈L形，苯环之间的二面角为82.5 (3)°。在晶体中，通过N-H⋯N氢键对连接的阳离子形成反演二聚体，该键由质子化的N原子产生。阳离子二聚体通过无序的氯离子通过N-H⋯Cl氢键连接成链，同时也存在N-H⋯O、C-H⋯O和C-H⋯Cl相互作用，这有助于巩固三维网络。
