Molecular packing in (I): (a) supramolecular dimer sustained by amide-N4—H⋯O2(carbonyl) hydrogen bonds (H atoms omitted for clarity), (b) layer where the dimers of (a) are connected by methylene-C3—H⋯N(azo) and benzene-C15—H⋯O1(amide) interactions [the methylene-C17—H⋯π(benzene) interactions occur within the dimers] and (c) a view of the unit-cell contents shown in projection down the a axis. The N—H⋯O, C—H⋯O and C—H⋯π interactions are shown as blue, orange and purple dashed lines, respectively. |
