摘    要:
以乙酰丙酮为共配体的稀土配合物与2-羟基苯取代的自由基配体进行反应得到2个新颖的稀土-自由基配合物[Ln2(acac)4(NIT-PhO)2](Ln=Tb(1),Y(2);acac=乙酰丙酮,NIT-PhOH=2-(2''-hydroxyphenyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide)。2个配合物的结构相同,均是通过2个自由基配体上的羟基氧原子桥联2个稀土离子构成双核结构。直流磁化率的研究表明配合物2具有弱的反铁磁性质。

关 键 词:稀土配合物  晶体结构  磁性质  自由基

Abstract:
The reaction of Ln(acac)3·3H2O with NIT-PhOH radical yielded two new Ln-radical complexes[Ln2(acac)4(NIT-PhO)2] (Ln=Tb (1), Y (2); acac=acetylacetonato, NIT-PhOH=2-(2''-hydroxyphenyl)-4,4,5,5-tetramethylimidazo-line-1-oxyl-3-oxide). Two complexes are isostructural and have binuclear structure in which two lanthanide ions are bridged by two radical ligands through their phenoxo-O atoms. DC magnetic susceptibility studies indicated that there exists weak antiferromagnetic interaction in complex 2.
Keywords:lanthanide complexes  crystal structure  magnetic properties  radical
