摘　　要：用硫酸钆与水杨醛氨基酸Ｓｃｈｉｆ碱，在水溶液中反应，合成了五种新的配合物，通式为Ｇｄｍ（ＳａｌＡＡ）ｎ（ＳＯ４）ｐ·ｘＨ２Ｏ（式中Ｓａｌ＝水杨醛、ＡＡ＝甘氨酸、Ｌ谷氨酸、Ｌ蛋氨酸、Ｌ胱氨酸和Ｌ赖氨酸，ｍ＝１～４，ｎ＝１～２，ｐ＝０、１、２，ｘ＝３、８、１２）。通过元素分析、摩尔电导、红外光谱、荧光光谱、紫外－可见光谱、差热热重分析对合成配合物的组成、性质进行了研究。Five new complexes of gadolinium sulphate with Schiff base ligands derived from salicylaldehyde and amino acids have been synthesized in aqueous solution. It is concluded that general formula of the five complexes are Gd m(Sal AA) n(SO 4) p·xH 2O(Sal=salicylidene,AA=glycine,L glutamic acid,L methonine,L lysine and L cystine, m=1～4,n=1～2,p=0,1,2,x=3,6,8,12).The composition and properties of complexes have been studied by elemental analysis, molar conductance, infrared, eletronic and fluorescence spectra,thermogravimetric and differential thermal analysis.
