Figure 4
The molecular packing in (I): (a) linear, supramolecular chain along the a axis 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, and (b) a view of the unit-cell contents in projection down the a axis. The methyl-C—H⋯O(hydroxy) and π–π interactions are shown as green and purple dashed lines, respectively. |
