The dianion of the title salt, 2C(5)H(6)N(+)·C(12)H(6)N(2)O(4)S(2) (2-), lies on a special position of 2 site symmetry that relates one thio-nicotinate part to the other, and the dihedral angle between the niotinate planes is 89.2 (2)°. The pyridinium cations are hydrogen bonded to the carboxyl-ate group by way of N-H⋯O links.
标题盐的双负离子2C₅H₆N⁺·C₁₂H₆N₂O₄S₂²⁻处于二重特殊位置，该位置将一个硫代烟酸部分与另一个相关联，且烟酸酯平面之间的二面角为89.2 (2)°。吡啶鎓阳离子通过N—H⋯O键与羧酸根基团形成氢键。
