Figure 2
(a) A fragment of the mono-periodic supramolecular columns formed by stacking of molecules along the c axis. (b) Di-periodic supramolecular layers formed by stacking of the supramolecular columns. For a better representation, each column has a different colour. Red dashed lines represent weak hydrogen bonds. (c) Stacking of the di-periodic layers along the c axis. Blue shaded areas correspond to the interlayer space without intermolecular interactions shorter than the sum of the van der Waals radii. The methanol molecules are not shown for clarity. |
