摘要
The simultaneous TG/DTG-DTA technique was used for three new cobalt(II) complexes with dipyridylamine (dpamH) and the anion of a 2-hydroxyphenone ligand (phenone), with the general formula [Co(dpamH)(2)(phenone)]Br, in order to determine their thermal degradation in static air and dynamic nitrogen atmospheres, which was found to be a multi-step decomposition related to the release of the ligand molecules. The complexes were characterized by elemental analyses, FT-IR and UV-Vis spectroscopy, magnetic and conductivity measurements. All structures were determined by X-ray crystallography revealing octahedral coordination of cobalt(II) and monomeric nature of the compounds, [Co(dpamH)(2)(2-OH-acetophenone)]Br (1), [Co(dpamH)(2)(2-OH-propiophenone)]Br (2) and [Co(dpamH)(2)(2-OH, 5-CH3-acetophenone)]Br center dot EtOH (3). The variable temperature (76-303 K) magnetic susceptibility measurements showed a paramagnetic nature of the complexes, in accordance with their molecular structure.
