| Özet |
| Three new cadmium–3-fluorobenzoate complexes with pyridine-3-carboxamide/pyridine-3-carboxylate complexes, namely, [Cd2(C7H4FO2)4(C6H6N2O)2(H2O)2] (1), [Cd2(C7H4FO2)4(C6H6N2O)2(H2O)2] (2), [Cd(C7H4FO2)(C6H4NO2)(H2O)] (3) were obtained under classical and two different hydrothermal conditions, respectively. The structures of all prepared complexes were characterized by elemental analysis, FT-IR and 1H NMR spectroscopy, TGA/DTA and single crystal X-ray analyses. In addition, the structural features of the complexes were studied theoretically by Hirshfeld surface analysis and the X-ray diffraction analyses were supported. It was determined that the carboxylate groups of 3-fluorobenzoate and pyridine-3-carboxylate behaved as chelating bidentate ligands. Hirshfeld surface analysis indicated that H⋯H, H⋯O/O⋯H, H⋯C/C⋯H, H⋯F/F⋯H and C⋯C interactions are the significant contributors to the crystal packing of the synthesized complexes. The thermal stabilities of the synthesized complexes have been investigated and the results showed that the complexes display thermal stability about 100 °C and the decomposition product of anhydrous complexes was CdO. The linear absorption and fluorescence (emission) properties of the complexes were investigated by using UV–Vis and Fluorescence spectroscopic techniques, respectively. It was found that the complex 1 which is synthesized by classical method has got very good emission intensity compared to the materials reported in the literature. This makes the complex 1 potential member for image acquisition without lens and filter, security printing, data recording and storage and laser applications, if its solid form can be done. In addition, it was determined that the classical synthesis has superiority according to the hydrothermal synthesis on the structural, optical absorption and fluorescence properties of the complex. |
