Özet
In the title complex, [Zn(C8H5O3) 2(C6H6N2O)2(H 2O)2], the ZnII cation is located on an inversion center and is coordinated by two 4-formyl-benzoate (FB) anions, two nicotinamide (NA) ligands and two water mol-ecules. The four O atoms in the equatorial plane around the ZnII cation form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate 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 mol-ecule links with the carboxyl-ate 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 inter-action link the mol-ecules into a two-dimensional network parallel to (010). These networks are linked via C-H⋯O and π-π inter-actions between inversion-related benzene rings [centroid-centroid distance = 3.8483 (7) Å], forming a three-dimensional supra-molecular structure.
