硫酸钕与氨基酸Schiff碱双核配合物的合成与表征

Synthesis and Characterization of Binuclear Complexes of Neodymium Sulphate with Amino Acid Schiff Bases

在温和条件下 ,用硫酸钕与水杨醛缩氨基酸Schiff碱在水溶液中反应 ,合成了钕的两种双核配合物Nd2 (Sal-a .a) 2 SO4·2H2 O(Sal=水杨基 ;a .a =L 丙氨酸 ,L 赖氨酸 ) ,并用元素分析、摩尔电导、红外光谱、电子光谱、荧光光谱和差热 -热重分析对其组成和性质进行了研究 .

Two new complexes of neodymium sulphate with N-salicylidene amino acid Schiff bases have been synthesized in aqueous solution on quite mild condition. It is concluded that their formulas are Nd 2(Sal-a.a)2SO 4·2H 2O (Sal=salicylidene; a.a=L-Ala, L-Lys).Their composition and properties of the complexes have been studied by elemental analysis, molar conductance, infrared, electronic and fluorescence spectra, thermogravimetric and differential thermal analysis.
