The mol­ecular packing in (II)[link]: (a) linear, supra­molecular tube along [901] sustained by charge-assisted amine-N—H⋯O(carboxyl­ate) and hy­droxy-O—H⋯O(carboxyl­ate) hydrogen-bonding inter­actions shown as blue and orange dashed lines, respectively; intra­molecular amine-N—H⋯O(carboxyl­ate) hydrogen bonds are represented by pink dashed lines, (b) end-on view of the supra­molecular tube and (c) a view of the unit-cell contents in projection down the c axis. The methyl­ene-, methyl-C—H⋯O(nitro) and π–π inter­actions are shown as green and purple dashed lines, respectively. In each of (a) and (b), non-participating H atoms are omitted.
