The packing arrangements in 4, showing the main (a) O—H⋯O and (b) C—H⋯O intermolecular interactions, and (c) layers, viewed from the crystallographic a direction. Hydrophobic layers (blue) found in 1–3 alternate with layers (green) which contain water molecules of crystallization (red and green voids) together with the aromatic rings. |
