Özet
Two new complexes, [Co(3-fba) 2 (na) 2 (H 2 O) 2 ] (1) and [Ni(3-fba) 2 (na) 2 (H 2 O) 2 ] (2) (where 3-fba = 3-fluorobenzoate and na = pyridine-3-carboxamide, nicotinamide), were synthesized and characterized using different techniques (elemental analysis, FT-IR, UV-Vis spectrophotometer, single-crystal X-ray diffraction, fluorescence spectroscopy, and TGA/DTA analysis). X-ray structural analysis revealed that 1 and 2 are isostructural and exhibit distorted octahedral coordination geometry. In each molecule, metal atoms (Co +2 and Ni +2 ) are linked by two 3-fluorobenzoate anions, two pyridine-3-carboxamide ligands, and two water molecules per formula unit. The 3-fluorobenzoate and pyridine-3-carboxamide are monodentate through a carboxylate oxygen atom and the nitrogen atom of the pyridine ring, respectively. UV-Vis results showed that the studied complexes have absorption edges similar to semiconductor structures. Namely, 1 and 2 indicated emission behaviors around 370 nm and 361 nm, respectively.
