Figure 2
Part of the crystal structure of (I), showing the formation of a chain of edge-fused R(12) rings along [010]. For the sake of clarity, H atoms bonded to C atoms have been omitted. Atoms marked with an asterisk (*), hash (#), dollar sign ($), ampersand (&) or `at' sign (@) are at the symmetry positions (x, 1 + y, z), ( − x, + y, −z), ( − x, y − , −z), (x, y − 1, z) and ( − x, + y, −z), respectively. |
