Figure 4
The polymeric ribbons with ladder-type hydrogen bonding formed in (5j)[link] by the (MeO)2cDHAP anions (solid lines) and cha cations (open lines) along the a axis. N+—H⋯O− hydrogen bonds are shown as dashed lines. H atoms not involved in hydrogen bonding have been omitted for clarity. [Symmetry codes: (ii) x − 1, y, z; (v) x − [{1\over 2}], −y + [{1\over 2}], −z + 1.]
