Abstract: The cations and anions of the title salt, 3C₆H₁₆N⁺·HSO₄^-·SO₄^2-, are linked by N-HO and O-HO hydrogen bonds into a three-dimensional network. The hydrogensulfate ion, with a single S-O(H) bond of 1.563 (2) Å, forms a short O-HO hydrogen bond [OO = 2.609 (2) Å] to the sulfate ion. The hydrogensulfate ion accepts two hydrogen bonds from two cations, whereas the sulfate ion, as an acceptor, binds to four cations. The sulfate ion is disordered approximately equally over two sites related by rotation around one of the O-S bonds.
