title: Bis(2-amino-thia-zolium) succinate succinic acid.
abstract: In the title compound, 2C(3)H(5)N(2)S(+)·C(4)H(4)O(4) (2-)·C(4)H(6)O(4), the thia-zolium 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-amino-thia-zole mol-ecule is protonated. Both the anion and the acid lie across inversion centres. The crystal packing is consolidated by inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds. Mol-ecules are stacked down the b axis.
