%X In the title compound (systenatic name: 3,4,5-trihydroxybenzoic acid pyridine monosolvate), C5H5N¡¤C7H6O5, the gallic acid molecule is essentially planar (r.m.s deviation = 0.0766   for non-H atoms) and is linked to the pyridine molecule by an O¡ªH...N hydrogen bond. An intramolecular O¡ªH...O hydrogen bond occurs in the gallic acid molecule. The gallic acid and pyridine mean planes make a dihedral angle 12.6 (3)¡ã. Intermolecular O¡ªH...O and O¡ªH...N hydrogen bonding involving the hydroxy and carboxyl groups and the pyridine molecule, and ¦Ð¨C¦Ð interactions between inversion-related pyridines [centroid¨Ccentroid distance = 3.459 (6)  ] and between pyridine and benzene rings [centroid¨Ccentroid distance = 3.548 (6)  ], lead to a three-dimensional network in the crystal.
