Projection of the crystal structure of (II) at 150 (2) K along [010] showing alternating hydrophilic and hydrophobic layers parallel to (001). In the hydrophilic region N1—H1⋯O5 (x, y, z) hydrogen bonds dominate, whereas in the hydrophobic part weak edge-to-face interactions between aromatic rings [C5—H5⋯Cg1 (−x + ½, y + ½, −z + ¼) and C12—H12⋯Cg1 (x − 1, y, z), not marked in this drawing] are observed. |
