The two bridging FB anions, one chelating FB anion and one nicotinamide (NA) ligand coordinate to one Zn cation with a distorted square-pyramidal geometry, while the two bridging FB anions, one monodentate FB anion and one NA ligand coordinate to the other Zn cation with a distorted tetrahedral geometry. Within the binuclear molecule, the pyridine rings are oriented at a dihedral angle of 19.41 (14)degrees. In the crystal structure, the uncoordinated 2-fluorobenzoic acid molecules are linked by O-H center dot center dot center dot O hydrogen bonding, forming centrosymmetric supramolecular dimers. Intermolecular N-H center dot center dot center dot O hydrogen bonds link the complex molecules into a three-dimensional network. The pi-pi contacts between nearly parallel pyridine and benzene rings [dihedral angles of 19.41 (14) and 12.72 (16)degrees, respectively, centroid-centroid distances = 3.701 (2) and 3.857 (3) angstrom] may further stabilize the crystal structure. The fluorine atoms in two FB ligands are disordered over two positions, with occupancy ratios of 0.70:0.30.eninfo:eu-repo/semantics/openAccessArticle10.1107/S16005368090480892-s2.0-72049105562U98321578633Q3M160865WOS:000272244600094Q4
