Two new dialkylammonium thiosulfates, namely bis(diisopropylammonium) thiosulfate, 2C6H16N+·S2O32−, (I), and bis(tert-butylammonium) thiosulfate, 2C4H12N+·S2O32−, (II), have been characterized. The secondary ammonium salt (I) crystallizes withZ= 4, while the primary ammonium salt (II), with more hydrogen-bond donors, crystallizes withZ= 8 and a noncrystallographic centre of inversion. In both salts, the organic cations and thiosulfate anions are linked within extensive N—H...O and N—H...S hydrogen-bond networks, forming extended two-dimensional layers. Layers are parallel to (10\overline{1}) in (I) and to (002) in (II), and have a polar interior and a nonpolar hydrocarbon exterior. The layered structure and hydrogen-bond motifs observed in (I) and (II) are similar to those in related ammonium sulfates.

The title compound, 2C12H20N+·C2H4O6S2 2−·2H2O, crystallizes with the edisylate anion situated on a center of inversion. All conventional hydrogen-bond donors and acceptors are utilized, forming two-dimensional sheets.
