Catena-Poly[[(4-Formyl­Benzoato-Κo1)(Isonicotinamide-Κn1) Zinc(Ii)]-Μ-4-Formyl­Benzoato-Κ2 O1:O1′]

Abstract

In the title compound, [Zn(C8H5O3)2(C6H6N2O)]n, the ZnII 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)°. 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—H⋯O and C—H⋯O hydrogen bonds, π–π contacts between the formyl­benzoate rings [centroid–centroid distance = 3.7736 (8) Å] and weak C—H⋯π inter­actions, forming a three-dimensional network.
