W. A. Yehye, A. Ariffin, N. A. Rahman and S. W. Ng

Abstract: The dianion of the title salt, 2C₅H₆N⁺·C₁₂H₆N₂O₄S₂^2-, lies on a special position of 2 site symmetry that relates one thionicotinate part to the other, and the dihedral angle between the niotinate planes is 89.2 (2)°. The pyridinium cations are hydrogen bonded to the carboxylate group by way of N-HO links.
