【摘要】 由浓缩等摩尔稀土氯化物和甘氨酰替-L-亮氨酸水溶液制备了稀土与甘氨酰替-L-亮氨酸固体配合物。配合物组成为LnLCl₃·nH₂O（式中,L=甘氨酰替-L-亮氨酸;n=5,Ln=Eu;n=6,Ln=Tb,Ho和Tm）。用X射线光电子能谱研究了稀土与甘氨酰替-L-亮氨酸的配位作用。结果表明稀土与甘氨酰替-L-亮氨酸配合物中一些相关原子的电子结合能明显改变,并且发现铕配合物Eu_3d,谱峰有强的伴峰,对上述伴峰产生机理亦进行了讨论。更多还原

【Abstract】 The title complexes have been prepared by concentrating stoichiometric mixture （1:1） of lanthanide chloride and glycyl-L-leucine solution, and studied by XPS. The binding energy of O_1s, C_2p, Ln_3d, and Ln_4d changed because of coordination. Moreover satellite peaks arise in the spectra of Eu complex. The formation of satellite peak has been attributed to electron transfer.更多还原
