合成了五个水杨醛与ＤＬ－两氨酸Ｓｃｈｉｆｆ碱稀土配合物，通过元素分析，红外光谱和紫外光谱推测了配合物的可能结构。其通式为［Ｌｎ２Ｌ３］·４Ｈ２Ｏ（Ｌｎ＝ＬａＣｅＰｒＮｄＳｍ；Ｈ２Ｌ＝
Five rare earth complexes of salicylaldehyde with Schiff base of DL-2-amino acid were synthesized. The possible structures of the complexes were predicted by elemental analysis, IR and UV spectra. The general formula is [Ln2L3] 4H2O (Ln = LaCePrNdSm; H2L =
