In the title molecular salt, 2C3H10NO+·C10H6O6S22-, the cations and anions are associated via N-HO and O-HO hydrogen-bonding interactions, giving rise to a three-dimensional structure with zigzag rows of cations lying between rows of anions. The asymmetric unit contains one cation and one half-anion, which is related to the remainder of the molecule by an inversion center.
The title compound was studied as part of a search for simple ferroelectric compounds. For general background to ferroelectric metal-organic frameworks, see: Ye et al. (2006); Zhang et al. (2008, 2009, 2010); Fu et al. (2009).
