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 ZnII 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)degrees. The two benzene rings of the FB ions are oriented at a dihedral angle of 81.30 (5)degrees. In the crystal, adjacent polymeric chains interact via N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds, pi-pi contacts between the formylbenzoate rings [centroid-centroid distance = 3.7736 (8) angstrom] and weak C-H center dot center dot center dot pi interactions, forming a three-dimensional network.
