Figure 2
(a) The packing of (I[link]) in the crystal lattice. Atoms marked with an asterisk (*), dollar sign ($) or hash (#) are at the symmetry positions (1 + x, y, z), ([{1 \over 2}] − x, 1 − y, z − [{1 \over 2}]) and ([{3 \over 2}] + x, [{3 \over 2}] − y, 1 − z), respectively. (b) The packing of (II[link]) in the crystal lattice. Atoms marked with an asterisk (*), hash (#) or plus sign (+) are at the symmetry positions (−x, y − [{1 \over 2}], [{1 \over 2}] − z), (x − 1, y, z) and (1 − x, y − [{1 \over 2}], [{1 \over 2}] − z), respectively. For clarity, H atoms bonded to C atoms have been omitted from both figures.
