Molecular packing in (I): (a) supramolecular dimer sustained by imine-C—H⋯O(hydroxy) interactions, shown as blue dashed lines, which incorporates two hydroxy-O—H⋯N(hydrazinyl) hydrogen bonds, shown as orange dashed lines, (b) view of a supramolecular chain sustained by C—H⋯π interactions and (c) a view of the unit-cell contents in projection down the b axis, highlighting the stacking of supramolecular layers along the c axis. The π—π, C—H⋯π(chelate ring) and C—H⋯π(arene) interactions are shown as pink, brown and purple dashed lines, respectively. |
