Part of the crystal structure of compound (I)

, showing the formation by pairs of anions of a hydrogen-bonded R₂²(14) ring. The atoms marked with an asterisk (*) are at the symmetry position (−x, −y + 1, −z + 1). For the sake of clarity, the unit-cell outline, the 4,4′-bipy units and the partial-occupancy water molecules have all been omitted.
