In the title complex, [Zn(C8H5O3)2(C6H6N2O)2(H2O)2], the ZnII cation is located on an inversion center and is coordinated by two 4-formylbenzoate (FB) anions, two nicotinamide (NA) ligands and two water molecules. The four O atoms in the equatorial plane around the ZnII cation form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxylate group and the adjacent benzene ring is 24.13 (8)°, while the pyridine ring and the benzene ring are oriented at a dihedral angle of 88.52 (4)°. The coordinating water molecule links with the carboxylate group via an O—H⋯O hydrogen bond. In the crystal, N—H⋯O and O—H⋯O hydrogen bonds, and a weak C—H⋯π interaction link the molecules into a two-dimensional network parallel to (010). These networks are …
