Abstract: In the molecule of the title compound, 2C₄H₁₀N₃O₂⁺·SO₄^-, the cations are planar (r.m.s. deviations = 0.0144 and 0.0236 Å) and oriented at a dihedral angle of 62.30 (4)°. Intramolecular N-HO hydrogen bonds result in the formation of two planar six-membered rings. The cations are linked to the sulfate ion through intermolecular C-HO and N-HO hydrogen bonds, forming an R₂²(8) ring motif. In the crystal structure, intermolecular N-HO and C-HO hydrogen bonds link the molecules into a three-dimensional network.
