Abstract
In the title compound, C5H6N+·C4H5O6−, the pyridine molecule exists as a cation and the tartaric acid molecule as a semi-tartrate anion. The semi-tartrate anions are linked by O—H⋯O hydrogen bonds to form hollow columns running parallel to the a axis. The pyridinium cations, trapped in the columns, are linked to the semi-tartrate anions via strong N—H⋯O hydrogen bonds.
