Figure 2
Part of the crystal structure of (I), showing the formation of a ribbon along [100] containing R12(6) and R21(7) rings. For the sake of clarity, H atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*), a hash symbol (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions (− + x, − y, z), (−1 + x, y, z), ( + x, − y, z) and (1 + x, y, z), respectively. |
