Molecular packing in (II): (a) supramolecular helical chain aligned along [010] and sustained by O—H⋯O hydrogen bonding, with the solvent pyridine molecules attached via O—H⋯N hydrogen bonding, and (b) a view of the unit-cell contents in projection down the a axis. The O—H⋯S, O—H⋯N, C—H⋯S and π–π interactions are shown as orange, blue, pink and purple dashed lines, respectively. |
