Figure 2
Detail of a six-membered ring of H₂AsO₄^- groups in (I)

, in polyhedral representation, with attached organic cations. Only one disorder component of each cation is shown and the C-bound H atoms are omitted for clarity. The H

O parts of the O-H

O hydrogen bonds are coloured yellow and the H

O parts of the N-H

O hydrogen bonds are light blue. The As1* and As1# tetrahedra are generated by the symmetry operations (1 - x, 1 - y, 1 - z) and (1 - x, $[{1\over 2}]$ + y, $[{3\over 2}]$ - z), respectively.
