Figure 2
The molecular conformation and atom-numbering scheme for the 5-SSA²⁻ dianion (A), the 5-SSA⁻ monoanion (B), the two ammonium cations on general sites (centred at N1 and N2) and the two ammonium cations (N3 and N4) lying on twofold rotation axes in the asymmetric unit of (II)

. Inter-species hydrogen bonds are shown as dashed lines and displacement ellipsoids are drawn at the 50% probability level.
