| Özet |
| The asymmetric unit of the title compound, [Zn2(C7H 4FO2)4(C6H6N2O)2] ·C7H5FO2, consists of a binuclear ZnII complex bridged by two carboxyl groups of 2-fluoro-benzoate (FB) anions and a 2-fluoro-benzoic acid mol-ecule. 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 tetra-hedral geometry. Within the binuclear mol-ecule, the pyridine rings are oriented at a dihedral angle of 19.41 (14)°. In the crystal structure, the uncoordinated 2-fluorobenzoic acid mol-ecules are linked by O - H⋯O hydrogen bonding, forming centrosymmetric supra-molecular dimers. Inter-molecular N - H⋯O hydrogen bonds link the complex mol-ecules into a three-dimensional network. The π-π contacts between nearly parallel pyridine and benzene rings [dihedral angles of 19.41 (14) and 12.72 (16)°, respectively, centroid-centroid distances = 3.701 (2) and 3.857 (3) Å] 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. |
