在水和甲醇的混合液中合成了标题配合物[Co(phendione)(SO4)(H2O)].5H2O(phendione=1,10-菲啰啉-5,6-二酮),通过元素分析,红外光谱和热分析对配合物进行了表征。结果表明,配合物中Co(Ⅱ)与2个N原子和2个O原子形成4配位结构,其中2个N原子来自配体1,10-菲啰啉-5,6-二酮,2个O原子分别来自1个水分子和1个硫酸根离子。根据热分解曲线,初步探讨了该配合物的热分解机理,热分解最终产物为CoO。 The title complex [Co (phendione) (SO4) (H2O)]. 5H2O (phendione = 1,10-phenanthroline-5,6-dione) was synthesized in a mixture of water and methanol. Infrared spectroscopy and thermal analysis of the complexes were characterized. The results show that Co (Ⅱ) complexes with two N atoms and two O atoms to form a 4-coordinated structure, of which two N atoms are derived from ligand 1,10-phenanthroline-5,6-dione, 2 O atoms from a water molecule and a sulfate ion. According to the thermal decomposition curve, the thermal decomposition mechanism of the complex was discussed. The final product of thermal decomposition was CoO.
