Figure 2
Part of the crystal structure of compound (I), showing the formation of a chain of edge-fused R22(12) and R44(24) rings along [130]. For the sake of clarity, H atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($), an ampersand (&) or an `at' sign (@) are at the symmetry positions (1 − x, 1 − y, 1 − z), ( + x, + y, z), (− + x, − + y, z), ( − x, − y, 1 − z) and ( − x, − − y, 1 − z), respectively. |
