Figure 4
The network structure between [HDMAP·DMAP]⁺ cationic layers and HqSA⁻ anion layers. The intermolecular C—H⋯O hydrogen bonds and C—H⋯π interactions are shown as dashed lines. The R₃³(8) motifs of independent ion pairs formed by an intermolecular N—H⋯N hydrogen bond and two intermolecular C—H⋯O hydrogen bonds are also shown as dashed lines. [Symmetry codes: (v) x, −y + 1, z + $[{1\over 2}]$ ; (vi) x, −y + 2, z + $[{1\over 2}]$ ; (vii) x + 1, −y + 2, z + $[{1\over 2}]$ ; (viii) x − 1, −y + 1, z + $[{1\over 2}]$ .].
