Figure 4
Part of the crystal structure of compound (II), showing the formation of a chain of rings along [20]. For the sake of clarity, H atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*), a hash (#) or an ampersand (&) are at the symmetry positions (1 − x, 1 − y, 1 − z), (3 − x, −y, 1 − z) and (−2 + x, 1 + y, z), respectively. |
