Figure 7
Part of the crystal structure of (II), showing the formation of a [010] chain of edge-fused R22(10) rings. For the sake of clarity, H atoms not involved in the motif shown have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions (1 − x, + y, − z), (1 − x, − + y, − z), (x, 1 + y, z) and (x, −1 + y, z), respectively. |
