Three-dimensional hydrogen-bonded structures in the 1:1 proton-transfer compounds of l-tartaric acid with the associative-group monosubstituted pyridines 3-amino­pyridine, 3-carboxy­pyridine (nicotinic acid) and 2-carboxy­pyridine (picolinic acid)

Figure 9
A perspective view of the packing of the three-dimensional structure of (III)

in the unit cell, showing the extension of the sheet substructures across the c cell direction via the 2-carboxypyridinium cations. H atoms not involved in hydrogen bonding have been omitted for clarity. Hydrogen bonds are shown as dashed lines. (See Table 3

for symmetry codes.)
