Figure 17
Part of the crystal structure of isomer (V) showing the formation of a chain of edge-fused R22(22) rings along []. For the sake of clarity the H atoms not involved in the motif shown have been omitted. The atoms marked with an asterisk (*), a hash (#) or a dollar sign ($) are at the symmetry positions (1 − x, 1 − y, 1 − z), (1 + x, −1 + y, z) and (2 − x, −y, 1 − z), respectively. |
