Molecular packing in the crystal of (I): (a) a view of the supramolecular tape comprising three-molecule aggregates (sustained by carboxylic acid-O—H⋯N(pyridyl) hydrogen bonding shown as orange dashed lines) linked by amide-N—H⋯O(carbonyl) hydrogen bonding (blue dashed lines) and supporting benzoic acid-C—H⋯O(carbonyl) interactions (green dashed lines), (b) an end-on view of the tape viewed down [111], (c) a view of the supramolecular layer whereby the tapes of (a) are linked by short pyridyl-C—H⋯O(carbonyl) interactions and (d) a view of the unit-cell contents down the a axis. |
