Figure 5
Chains along the a axis in the structures of (a) (IV)[link] and (b) (V)[link]. Hydrogen bonds are shown as dashed lines. H atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry codes for (a): (i) [{1\over 2}] + x, −[{1\over 2}] − y, −z; (ii) 1 + x, y, z; (iii) −[{1\over 2}] + x, −[{1\over 2}] − y, −z. Symmetry codes for (b): (i) −[{1\over 2}] + x, [{3\over 2}] − y, −z; (ii) −1 + x, y, z; (iii) [{1\over 2}] + x, [{3\over 2}] − y, −z.]
