【摘要】 报道在水溶液中合成新型四氮杂四乙酸基取代大环H4L( 5,7,1 2 ,1 4-四甲基 -1 ,4,8,1 1 -四氮杂环十四烷 -N′,N″,N′″,N″″-四乙酸 )与Co(Ⅱ )、Ni(Ⅱ )的单核固体配合物。经元素分析、IR和UV光谱表征其组成为CoLH2 ·2H2 O和NiLH2 ·2H2 O。采用紫外———可见光谱研究了配合物在水溶液中的结构特征 ,并对所得结果进行了讨论。更多还原

【Abstract】 Two new complexes of H 4L(5,7,12,14-Tetramethyl-1,4,8,11-Tetraazamacrocyclotetradecane-N′,N″,N′″,N″″-tetraacetic acid) with Co(Ⅱ) and Ni(Ⅱ) have been synthesized in water solutions and characterized by elemental analysis and IR and UV spectra. The complexes have constant stoichiometry CoH 2L·2H 2O and NiH 2L·2H 2O. The structure of the complexes were discussed.更多还原
