甘氨酰甘氨酸、甘氨酰甘氨酰甘氨酸与硝酸铈（Ⅲ、Ⅳ）固体配合物的合成及表征

Synthesis and characterization of complexes of Digly and Trigly with cerium (Ⅲ、Ⅳ) nitrates

在水溶液中合成了硝酸铈（Ⅲ、Ⅳ）与甘氨酰甘氨酸（Ｄｉｇｌｙ）和甘氨酰甘氨酰甘氨酸（Ｔｒｉｇｌｙ）４种尚未见报道的固体配合物．经元素分析、红外光谱、热分析及核磁共振谱证明，配合物的组成为Ｃｅ（ＮＯ３）３·４Ｄｉｇｌｙ·４Ｈ２Ｏ；Ｃｅ（ＮＯ３）３·４Ｔｒｉｇｌｙ·３Ｈ２Ｏ；

Four unknown complexes of Digly and Trigly with cerium(Ⅲ、Ⅳ) nitrates have been synthesized in water.All of which are formed in the solid state.They are charactered by elemental analysis,infrared spectra, 1H nuclear magnetic resonance.The complexes have the compositions Ce(NO 3) 3·4L· n H 2O or Ce(NO 3) 4·2L· n H 2O(L=Digly or Trigly).
