Abstract: The title compound, 2C8H20N+·HSO4-·H2PO4-, was crystallized in a desiccator over P4O10 from a water solution of stoichiometric amounts of tetraethylammonium hydroxide and sulfuric and phosphoric acids. The compound is deliquescent. The structure contains two symmetry-independent cations in nearly the same conformation, as well as two symmetry-independent anions, the central atoms of which are equally occupied by P and S. The anions are interconnected by short O
O hydrogen bonds into one-dimensional chains. The distances and angles between some of the methyl or methylene groups and anionic O atoms indicate the presence of C-HO hydrogen bonds. The structure was determined from data at 292 (2) and 150 (2) K. These room- and low-temperature structures are virtually the same, with the exception of the localization of the H atoms that participate in the symmetry-restricted OO hydrogen bonds. A differential scanning calorimetry experiment indicated no phase transition below the temperature at which the compound started to decompose (353 K), down to 93 K.
