Figure 7
Part of the crystal structure of (III)[link], showing the ladder structure formed by the linking of two centrosymmetric rings. This ladder runs parallel to the a axis. Atoms labelled with an asterisk (*), hash (#), dollar sign ($), ampersand (&) and `at' symbol (@) are at the symmetry positions (−x + 1, −y + 1, −z + 1), (−x, −y + 1, −z + 1), (x + 1, y, z), (−x + 2, −y + 1, −z + 1) and (x − 1, y, z), respectively. H atoms not involved in hydrogen bonding have been omitted.
