| 摘 要： | 合成和鉴定了２组组成为Ｌｎ（Ｌ）（ＴＴＡ）３三元配合物（Ｌｎ＝Ｌａ，Ｎｄ，Ｅｕ，Ｔｂ，Ｙｂ；Ｌ１＝ｐｈｅｎＮＯ，Ｌ２＝ｂｉｐｙＮ２Ｏ２）．通过元素分析、电导测定、紫外、ＩＲ光谱对化合物组成进行了鉴定，并讨论了它们的稳定性和配位结构。荧光光谱研究表明，Ｅｕ（ｐｈｅｎＮＯ）（ＴＴＡ）３配合物中Ｅｕ３＋仅具有一种格位对称性，配合物不具有反演中心。

| Abstract: | The syntheses and characterizations of the title ternary complexes are reported. The composition Ln(L)(TTA)3 (Ln=La , Nd , Eu , Yb; L1=phenNO, L2= bipy N2O2) of the complexes are determined by elemental analysis, molar conductance, UV spectra and IR spectra. Their thermal stabilities and coordination structure are discussed. The fluorescence spectrum of 77K shows that Eu3+ in Eu(phenNO)(TTA)3 only has one kind of site syminetry and the complex has no inversion centre. |
