Molecular packing for (I): (a) the supramolecular double chain sustained by O—H⋯O and O—H⋯N hydrogen-bonding, shown as orange and blue, dashed lines, respectively, (b) a view of the immediate environment of one chain down the direction of propagation highlighting the role of C—H⋯O interactions (purple dashed lines) in sustaining the three-dimensional architecture and (c) a view of the unit-cell contents in projection down the b axis. |
