Figure 4 . ORTEP drawings of cation H (C20H27N2+) and anion D (C4H3O4−) in the asymmetric unit of (I) showing the atom numbering scheme and 50% probability displacement ellipsoids of non-H atoms. Dashed lines indicate N2H—H2HB⋯O4C and N2H—H2HB⋯O3D inter­molecular and O3D—H3D⋯O1D intra­molecular hydrogen bond inter­actions.
