Figure 6
Part of the crystal structure of (III) , showing the formation of a [110] chain of R22(8) and R44(26) rings. For clarity, H atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($), an ampersand (&) or an `at' sign (@) are at the symmetry positions (2 − x, 1 − y, 1 − z), (−1 + x, −1 + y, z), (1 − x, −y, 1 − z), (3 − x, 2 − y, 1 − z) and (1 + x, 1 + y, z), respectively. |
