Molecular packing in the title co-crystal: (a) three-molecule aggregate sustained by hydroxy-O—H⋯N(pyridyl) hydrogen bonds, (b) supramolecular layers whereby the aggregates in (a) are connected by amide-N—H⋯O(carbonyl) and methylene-C—H⋯O(amide) interactions, and (c) a view of the unit-cell contents shown in projection down the a axis, highlighting the intra- and inter-layer π–π interactions to consolidate a three-dimensional architecture. The O—H⋯N, N—H⋯O, C—H⋯O and π–π interactions are shown as orange, blue, green and purple dashed lines, respectively. |
