Molecular packing in the crystal of (I): (a) the four-molecule aggregate sustained by DTBA-O—H⋯O(DMF) and DTBA-O—H⋯O(DTBA) hydrogen bonding shown as orange dashed lines, (b) the supramolecular chain sustained by carbonyl-O⋯π(benzene) interactions shown as red dashed lines, (c) the supramolecular layer with benzene-C—H⋯O(DTBA) interactions shown as blue dashed lines and (d) a view of the unit-cell contents down the a axis with benzene-C—H⋯π(benzene) interactions shown as purple dashed lines. In (b) and (c) the non-participating H atoms have been omitted to aid clarity. |
