چکیده
IN THE TITLE COMPOUND (SYSTENATIC NAME: 3,4,5-trihy-droxy-benzoic acid pyridine monosolvate), C(5)H(5)N·C(7)H(6)O(5), the gallic acid mol-ecule is essentially planar (r.m.s deviation = 0.0766 Å for non-H atoms) and is linked to the pyridine mol-ecule by an O-H⋯N hydrogen bond. An intra-molecular O-H⋯O hydrogen bond occurs in the gallic acid mol-ecule. The gallic acid and pyridine mean planes make a dihedral angle 12.6 (3)°. Inter-molecular O-H⋯O and O-H⋯N hydrogen bonding involving the hy-droxy and carboxyl groups and the pyridine mol-ecule, and π-π inter-actions between inversion-related pyridines [centroid-centroid distance = 3.459 (6) Å] and between pyridine and benzene rings [centroid-centroid distance = 3.548 (6) Å], lead to a three-dimensional network in the crystal.
