摘要
通过对Ｅｕ（ＴＴＡ）４Ｐ络盐的合成，确定了它的分子组成。并对该络盐的紫外－可见光谱、红外光谱及偏振荧光光谱，核磁共振谱进行了测定分析，获得了该络盐的内部结构信息。判断出络合物配位体微环境的对称性不低于Ｃ２ｖ点群。
We have prepared a new complex salt, Eu(TTA)4P, and measured its UV absorption spectrum in methyl-sulfoxide and acetonitrile as well as its IR,fluoresence and 1HNMR spectra. From the observation, i. e., the constancy of fluoresence peak value before and after light polarization, and 1HNMR peaks remain the same in the course of complexing in the TTA moity, the inference can be drawn that there must exist a higher coordination field microenvironment inside the complex ion in the liquid statenot lower than C2v point group.
