Figure 15
Part of the crystal structure of (5), showing the formation of a sheet parallel to (001) built from a C(6) translational chain running parallel to [100], and C(5) and C(7) spirals running parallel to [010]. Atoms are depicted as in Fig. 6. The atoms marked with a prime (′), a star (*) or a hash (#) are at the symmetry positions (-1 + x, y, z), () and (), respectively. Methyl groups are omitted for the sake of clarity. |
