Part of the crystal structure of (II), showing the formation of a C(9) zigzag chain. For the sake of clarity, H atoms not participating in the hydrogen bonding have been omitted. Atoms marked with an asterisk (*) or hash (#) are at the symmetry positions (½ + x, 2 − y, z) and (−½ +−x, 2 − y, z), respectively. |
