Figure 3
The dimer of [O₃S–C₆H₄–PO₃H]²⁻ anions in (a) compound (I)

and (b) compound (II)

. H atoms attached to aryl C atoms have been omitted for clarity. The CPO₃ and CSO₃ groups are shaded in medium and light grey, respectively. O, C and H atoms are drawn as crossed, black and white spheres, respectively. Hydrogen bonds between [O₃S–C₆H₄–PO₃H]²⁻ anions and water molecules are represented by dashed lines. [Symmetry code: (i) −x, 1 − y, −z.]
