【摘要】 以糠醛缩5 氨基水杨酸为配体,合成了未见报道的 6 种稀土配合物,运用元素分析、红外、紫外、核磁共振氢谱、热重 差热分析、摩尔电导等手段对配合物的结构进行表征,证实配合物的组成为[RE(L2 )2Cl]·0.5C2H5OH( RE=La,Nd ) 或[RE(L2)2Cl]·nH2O ( RE=Gd,Dy,Yb,Y ),配体以负一价离子四齿形式配位,配位数为9.更多还原

【Abstract】 Six new rare earth complexes have been synthesized with the ligand Furfural-5-amino Salicylic Acid and characterized by IR, UV,¹HNMR spectra, TG-DTA, elemental analyses and molar conductance. The composition of complexes have been proved to be [RE（L₂）₂Cl]·0.5C₂H₅OH （ RE=La,Nd ） or [RE（L₂）₂Cl]·nH₂O （ RE=Gd,Dy,Yb,Y ）. Furfural-5-amino Salicylic Acid is quadridentate ligand and the coordination number is nine.更多还原
