摘　　要：本文报道了一个新的四核铽配合物[TbⅢ4(μ3-OH)2(L)4(piv)2(DMF)2]·2DMF(1)的合成、结构和磁学性质,其中席夫碱配体H2L是2-羟基-3-甲氧基-苯基水杨基亚胺,piv是特戊酸根离子。X射线单晶衍射显示该配合物具有平面"蝴蝶"形结构,由两个μ3-羟基氧原子和六个酚羟基氧原子桥接。磁性研究表明配合物1具有反铁磁性。This article reports the synthesis, structure and magnetic properties of a new tetranuclear terbium complex [TbⅢ4(μ3-OH)2(L)4(piv)2(DMF)2]·2DMF(1), in which Schiff base The ligand H2L is 2-hydroxy-3-methoxy-phenyl salicylimine, and piv is the pivalate ion. X-ray single crystal diffraction shows that the complex has a planar "butterfly" structure, bridged by two μ3-hydroxyl oxygen atoms and six phenolic hydroxyl oxygen atoms. Magnetic studies show that complex 1 has antiferromagnetism.
