Abstract: In the title compound, [Zn(C₈H₅O₃)₂(C₆H₆N₂O)]_n, the Zn^II ion is tetrahedrally coordinated by two formylbenzoate (FB) and one isonicotinamide (INA) ligands while symmetry-related FB ligands bridge adjacent Zn^II ions, forming polymeric chains along the b axis. The carboxylate groups in the two FB ions are twisted away from the attached benzene ring by 9.07 (2) and 26.2 (2)°. The two benzene rings of the FB ions are oriented at a dihedral angle of 81.30 (5)°. In the crystal, adjacent polymeric chains interact via N-HO and C-HO hydrogen bonds, - contacts between the formylbenzoate rings [centroid-centroid distance = 3.7736 (8) Å] and weak C-H interactions, forming a three-dimensional network.
