The cation of the title compound, C7H7N2S+·H2PO4-, is almost planar (r.m.s deviation = 0.017 Å for all non-H atoms). In the crystal structure, the cations and anions are connected by N-HO and O-HO hydrogen bonds, with - stacking interactions between neighbouring 1,3-thiazole and benzene rings [centroid-centroid distance = 3.5711 (11) Å], forming a three-dimensional network.
