Figure 4
Part of the crystal structure of (Ib) showing the linking of (100) sheets by means of aromatic ππ-stacking interactions. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), hash (#), dollar sign ($) or ampersand (&) are at the symmetry positions (−½ + x, y, ½ − z), (½ + x, y, ½ − z), (1 − x, ½ + y, ½ − z) and (1 − x, −½ + y, ½ − z), respectively.
