Figure 2
Part of the crystal structure of (I), showing the intersection of the [100] and [101] chains to form a sheet of R44(29) rings. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($), an ampersand (&) or an `at' sign (@) are at the symmetry positions (1 + x, y, z), ( + x, 1 − y, + z), (1 + x, y, 1 + z), ( + x, 1 − y, + z) and (2 + x, y, 1 + z), respectively. |
