Part of the crystal structure of (II) showing the formation of the C(9) spiral motif linking the [112] and [12] chains. Atoms marked with an asterisk (*) or hash (#) are at the symmetry positions (½ − x, ½ + y, −z) and (x, 1 + y, z), respectively. H atoms bonded to C atoms have been omitted for the sake of clarity. |
