experimental conditions were studied and the resulting complexes with the compositions [UO2(H2L2)(H2O)]n,[UO2(H2L2)]inn,3nH2O, [UO2(H3L2)(CH3COO)]n3nH2O, [UO2Zn(L2) (H2O)2]n2nH2O, [(UO2)2(H2L2)(C2O4)]n2nH2O and [(UO2)2(L2)(py)2(H2O)4] were characterized on the basis of elemental analyses, EDAX and thermoanalytical data. The structural assessment of the complexes was carried out by using molar conductance, magnetic
摘要在不同的实验条件下,研究了二水杨醛己二酰二hydr与乙酸铀酰二水合物和硝酸铀酰六水合物在水和乙醇介质中的反应,得到了具有[UO2(H2L2)(H2O)] n,[UO2(H2L2)] inn组成的配合物。 3nH2O,[UO2(H3L2)(CH3COO)] n3nH2O,[UO2Zn(L2)(H2O)2] n2nH2O,[(UO2)2(H2L2)(C2O4)] n2nH2O和[(UO2)2(L2)(py)根据元素分析,EDAX和热分析数据对2(H2O)4]进行了表征。通过使用摩尔电导,磁矩和ESR数据以及IR,电子和1H NMR光谱对配合物进行结构评估。在配合物中,配体起桥接一元四齿,二元六齿和四元六齿配体的作用,并表现出酮-烯醇互变异构现象。乙酸酯和草酸酯基团充当螯合双齿和桥接四齿配体。络合物被认为涉及七个,八个,九个和十个配位铀原子,配体原子排列在围绕线性铀酰基团的赤道平面中,并且在
