Molecular packing in (I)

, showing (a) the supramolecular ladders aligned along the a axis and sustained by O—H⋯O hydrogen bonding, (b) the supramolecular layers parallel to the ab plane whereby the ladders in (a) are connected by O—H⋯S and C—H⋯O interactions, and (c) a view of the unit-cell contents in projection down the a axis, showing C—H⋯S interactions along the c axis connecting the layers in (b). The O—H⋯O, O—H⋯S, C—H⋯O and C—H⋯S interactions are shown as orange, blue, pink and green dashed lines, respectively.
