Figure 9
Part of the crystal structure of (III), showing the hydroxy–water hydrogen-bonded chain which runs parallel to the a axis. Atoms labelled with an asterisk (*), hash (#), dollar sign ($) and ampersand (&) are at the symmetry positions (−x + , y + , −z + ), (−x + , y + , −z + ), (x + 1, y, z) and (x − 1, y, z), respectively. The pendant molecules at (x, y, z), (x + 1, y, z) and (x − 1, y, z) are not involved in the chain. H atoms not involved in hydrogen bonding have been omitted. |
