H.-K. Fun, J. John, S. R. Jebas and T. Balasubramanian

Abstract: In the title compound, 2C₃H₅N₂S⁺·C₄H₄O₄^2-·C₄H₆O₄, the thiazolium ring is almost planar, with the maximum deviation from planarity being 0.0056 (8) Å for the C atom carrying the amine substituent. The N atom of the 2-aminothiazole molecule is protonated. Both the anion and the acid lie across inversion centres. The crystal packing is consolidated by intermolecular O-HO, N-HO and C-HO hydrogen bonds. Molecules are stacked down the b axis.
