稀土与甘氨酸作用形成固体配合物的研究工作已有许多。但用稀土硝酸盐与甘氨酸作用生成固体配合物的工作尚未见文献报道，而红外光谱的研究也未开展，本工作在水相中制得了Ｌａ、Ｃｅ、Ｐｒ、Ｎｄ、Ｓｍ、Ｅｕ、Ｇｄ、Ｔｂ、Ｙ共９种稀土硝酸盐与甘氨酸固体配合物，测量了配合物的ＦＴ－ＩＲ光谱，对其主要红外吸收带进行了归属，同时也对配合物配位键性质进行了探讨。 Rare earth and glycine role in the formation of solid complexes have been many studies. However, the work of using rare earth nitrate and glycine to generate solid complexes has not been reported in the literature, and the research of infrared spectroscopy has not been carried out yet. In this work, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb and Y were synthesized. The FT-IR spectra of nine rare earth nitrate and glycine complexes were measured and their main infrared absorption bands were assigned. At the same time, the coordination properties of the complexes were also discussed.
