Figure 4
Fragment of the crystal structure of (1), showing the polar hydrogen-bonded anionic chains propagating along the b-axis direction, in the environment of the Rb cations. Blue lines indicate a pseudo-primitive cubic net arrangement of the cations, with every cell populated by a single anion (c.f. the structure of CsCl).
