The molecular packing in (I): (a) immediate environment about the [H2NNH3] cation, (b) supramolecular chain comprising anions and water molecules only, orientated along the b axis and sustained by water-O—H⋯O(carboxylate) hydrogen bonding, (c) decoration of the chain of (b) with cations and additional water molecules to highlight the formation of various supramolecular synthons (see text) and (d) a view of the unit-cell contents in projection down the b axis. The O—H⋯O, N—H⋯O, N—H⋯N and intramolecular N—H⋯O hydrogen bonds are shown as orange, blue, brown and pink dashed lines, respectively. In (b) and (c), all but the CO2 groups of the two central benzoate residues have been removed for clarity. |
