Figure 3
Part of the crystal structure of (VII), showing the formation of a hydrogen-bonded C(4) chain running parallel to [100]. For the sake of clarity, H atoms bonded to C atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*) or a hash symbol (#) are at the symmetry positions (x + 1, y, z) and (x − 1, y, z), respectively. |
