合成了稀土与 6 甲基皮考林酸氮氧化物 (HL)及 2 ,2′ 联吡啶 N ,N′ 二氧化物 (bipyO2 )的三元固体配合物LnL3bipyO2 ·nH2 O(Ln =La3+ ,Sm3+ ,Eu3+ ,Gd3+ ,Tb3+ ,Dy3+ ,Yb3+ )。元素分析、差热 热重分析、红外光谱、摩尔电导及X射线粉末衍射等分析结果表明 :配合物的组成为 {Ln(C7H6 O3N) 3·(C10 H8N2 O2 )·H2 O}(n -1 )H2 O(n =2 5～ 3 0 )。荧光光谱表明 :三元配合物LnL3bipyO2 ·nH2 O的荧光强度比二元配合物LnL3·mH2 O的要弱 ,与二元配合物不同的是 :TbL3bipyO2 ·3H2 O在 4 89 3nm处峰的相对强度比 543 8nm处峰的相对强度要强。
The ternary solid complexes LnL3bipyO2 · nH2O (Ln = La3 +, Sm3 +) of rare earth with 6 picolinic acid oxynitride (HL) and 2,2’- bipyridine bipyridyl (bipyO2) , Eu3 +, Gd3 +, Tb3 +, Dy3 +, Yb3 +). The results of elemental analysis, TG-DTA, FT-IR, molar conductance and X-ray powder diffraction show that the composition of the complex is {Ln (C7H6O3N) 3 · (C10H8N2O2) · H2O} ) H2 O (n = 25 ~ 30). Fluorescence spectra show that the fluorescence intensity of the ternary complex LnL3bipyO2 · nH2O is weaker than that of the binary complex LnL3 · mH2O, which is different from the binary complexes: the relative intensity of the peak of TbL3bipyO2 · 3H2O at 4 893 nm The peak intensity is stronger at 543 nm than at 543 nm.
