Figure 4
Part of the crystal structure of (II) showing the formation of the C22(11) spiral motif linking the [112] and [12] chains. Atoms marked with a hash (#) or dollar sign ($) are at the symmetry positions (x, 1 + y, z) and (½ − x, ½ + y, 1 − z), respectively. H atoms bonded to C atoms and some leucyl alkyl C atoms have been omitted for the sake of clarity. |
