The molecular packing in (I), showing (a) supramolecular chain comprising anions only, orientated along the c axis and sustained by amino-N—H⋯O(carboxylate) interactions shown as orange dashed lines, (b) detail of the 12-membered {⋯HNH⋯OCO}2 synthon with ammonium-N—H⋯O(carboxylate) hydrogen bonds shown as blue dashed lines and (c) a view of the unit-cell contents in projection down the c axis. In part (b), all but the CO2 groups of the two central benzoate residues have been removed for clarity. |
