| 摘要: 合成了并通过单晶衍射表征了2个同构稀土配合物[LnL2(NO3)3](L=N,N-二苯基-2-(8-喹啉氧基)乙酰胺,Ln=La(Ⅲ),1;Ce(Ⅲ),2)。在每个配合物中,十二配位的稀土离子采取扭曲的二十面体配位构型,分别与来自2个配体的4个氧原子和2个氮原子及来自3个双齿配位硝酸根的6个氧原子配位。乙腈溶液中,配合物发射强荧光。 |

| Abstract: Two isostructural lanthanide complexes, [LnL2(NO3)3] (L=N,N-diphenyl-2-(quinolin-8-yloxy)acetamide, Ln=La(Ⅲ), 1; Ce(Ⅲ), 2) were synthesized and characterized by X-ray diffraction. In each complex, center metal ion is coordinated to four oxygen and two nitrogen atoms from two independent acetamide ligands and also to six oxygen atoms from three nitrate anions, possessing a coordination geometry closer to a distorted icosahedron. In CH3CN solution, both complexes exhibit strong fluorescence emission. CCDC: 941145, 1; 941146, 2. |
