In the title compound, C(16)H(14)NS(+)·C(6)H(4)BrO(3)S(-), the cation exists in an E configuration and is essentially planar, the dihedral angle between the quinolinium and thio-phene rings being 3.45 (9)°. The anion is inclined to the cation with dihedral angles of 75.43 (8) and 72.03 (11)°, respectively between the benzene ring and the quinolinium and thio-phene rings. In the crystal, the cations and anions are arranged individually into separate chains along the c axis. The cation chains are stacked in an anti-parallel manner along the a axis by π⋯π inter-actions with centroid-centroid distances of 3.7257 (13) and 3.7262 (14) Å. Weak C-H⋯O and C-H⋯π inter-actions link the cations and anions into a three-dimensional network. Short Br⋯S [3.7224 (5) Å] and Br⋯O [3.4267 (16) Å] contacts are also observed.
在标题化合物C(16)H(14)NS(+)·C(6)H(4)BrO(3)S(-)中，阳离子呈E构型且基本为平面结构，喹啉鎓环与噻吩环之间的二面角为3.45 (9)°。阴离子相对于阳离子倾斜，苯环与喹啉鎓环和噻吩环之间的二面角分别为75.43 (8)°和72.03 (11)°。在晶体中，阳离子和阴离子沿着c轴分别排列成单独的链。阳离子链通过π⋯π相互作用沿a轴以反平行方式堆积，质心间距为3.7257 (13)和3.7262 (14) Å。弱的C-H⋯O和C-H⋯π相互作用将阳离子和阴离子连接成三维网络。还观察到短的Br⋯S [3.7224 (5) Å]和Br⋯O [3.4267 (16) Å]接触。
