Figure 3 Interdigitation between parallel zigzag chains and hydrogen bonding. View is down the c axis along the direction of the polymeric chains shown in Fig. 2. Note the interdigitation of tolyl groups of parallel chains along the a axis and the water filled areas between chains along the b axis. Hydrogen bonds are indicated by dashed light blue lines. Bands of H–bonded water molecules stretch infinitely parallel to the a axis. |
