Bis(trimethylammonium) naphthalene-1,5-disulfonate

Y. Jin

Abstract: The asymmetric unit of the title compound, 2C₃H₁₀N⁺·C₁₀H₆S₂O₆^2-, contains a half-anion, which is completed by inversion symmetry, and one cation. The cations and anions are associated via strong N-HO(sulfonate) hydrogen-bonding interactions, forming cation-anion-cation groups. Secondary interactions such as C-H(ammonium)O(sulfonate) and van der Waals interactions link the cations and anions together in a three-dimensional crystal structure, with zigzag rows of cations lying between layers of anions.
