Figure 3
Parts of the crystal structures of (a) (II)[link] and (b) (IV)[link], showing the formation of C(4) chains along [100]. Dashed lines indicate hydrogen bonds. For the sake of clarity, H atoms bonded to C atoms not involved in the motifs shown have been omitted. Atoms marked with an asterisk (*) or a dollar sign ($) are at the symmetry positions (−1 + x, y, z) and (1 + x, y, z), respectively.
