摘　　要：以氮氧自由基为配体,合成了2例未见文献报道的氮氧自由基-稀土配合物[Dy(hfac)3(NIT-C_3H_5)(H_2O)]与[Dy(hfac)3(NITC3H5)]n(hfac=六氟乙酰丙酮,NIT-C3H5=2-环丙烷基-4,4,5,5-四甲基-2-咪唑啉-3-氧化-1-氧基自由基)。单晶结构分析表明配合物1为单核结构,单斜晶系P21/c空间群;配合物2为一维结构,单斜晶系P21/c空间群。交流磁化率测试结果表明配合物2虚部表现出频率依赖,这表明配合物2是单链磁体。Two Dy（Ⅲ）-nitrony] nitroxide radical complexes [Dy（hfac）3（NIT-C3Hs）（H20）] and [Dy（hfac）3（NIT-C3H5）]（NIT-C3Hs=2-cyclopropyl-4, 4, 5, 5-tetramethyl-imidazoline-l-oxyl-3-oxide, hfac=hexafluoroacetylacetonate）, have been successfully prepared with different synthetic condition. Single crystal X-ray crystallographic analyses reveal that complex 1 is mononuelear complex which crystallize in the P2I/c space group while complex 2 is one- dimensional complex which crystallize in the P2I/c space group as well. Magnetic studies reveal that complex 2 exhibits frequency-dependence of ac magnetic susceptibilities, indicating that it behaves as single-chain magnet.
