Figure 4
Part of the crystal structure of (II), showing the formation of a hydrogen-bonded (dashed lines) chain parallel to [010]. For the sake of clarity, H atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*), a hash (#), a dollar sign ($) or an ampersand (&) are at the symmetry positions (−x + 1, y + , −z + ), (−x + 1, y − , −z + ), (x, y + 1, z) and (x, y − 1, z), respectively. |
