| 摘要: 合成并通过单晶衍射表征了3个同构稀土配合物Ln(L)(NO3)3(H2O)(L=N-苯基-2-(5-氯-8-喹啉氧基)乙酰胺,Ln=Pr(Ⅲ),1;Nd(Ⅲ),2;Sm(Ⅲ),3)。在每个配合物中,十配位的稀土离子采取扭曲的双帽四方反棱柱配位构型,分别与来自1个配体L的2个氧原子和1个氮原子,2个双齿配位硝酸根和1个水分子配位。配合物3能够发射Sm(Ⅲ)离子特征荧光,荧光寿命为11.7μs。 |

| Abstract: Three lanthanide(Ⅲ) complexes Ln(L)(NO3)3(H2O) [Ln=Pr(1), Nd(2) and Sm(3)] based on L(L=N-phenyl-2-(5-chloro-quinolin-8-yloxy) acetamide) have been synthesized and characterized by elemental analyses, IR spectra and X-ray diffraction analyses.The results reveal that the Ln(Ⅲ) ion in each complex is surrounded by one tridentate L with NO2 donor set, three bidentate nitrate anions and one water molecule, thus giving bicapped square antiprism coordination geometry.In addition, complexes 3 could exhibit characteristic fluorescent emissions of the Sm(Ⅲ) ion in the visible region with the average lifetime being 11.7μs.CCDC:1419222, 1; 1419223, 2; 1419224, 3. |
