以N,N'-二(4-甲氧基水杨基)邻苯二胺(H2L)为配体合成了2个新的稀土配合物[M2L3(H2O)](M=Tb (1),Dy(2)),并对它们进行了红外分析、元素分析和单晶结构分析.单晶衍射结果表明,配合物1和2均为三明治型双核配合物.此外还研究了配合物1和2的磁学性质,结果表明配合物1和2都表现出反铁磁性作用和场诱导效应引起的慢弛豫行为.配合物2的有效能垒和驰豫时间分别为35.45 cm-1和2.7×10-10s.%Two new sandwich-type di-lanthanide complexes [M2L3 (H2O)] (M =Tb (1),Dy (2),H2L=N,N'-bis (4-methyloxysalicylidene)benzene-1,2-diamine) were synthesized by treating the Schiff-base ligand with M(acac)3·6H2O (M=Tb,Dy) and characterized by elemental analysis,IR spectra and X-ray single crystal diffraction.X-ray single crystal diffraction analysis reveals that 1 and 2 have a similar new triple-deck dinuclear sandwich structure.The magnetic measurements of complexes 1 and 2 indicated that 1 and 2 exhibit the antiferromagnetic interactions between lanthanide ions,and field-induced slow magnetic relaxation.The deduced effective energy barrier (Ueff) and relaxation time (τ0) are 35.45 cm-1 and 2.7×10-10 s for 2.CCDC:1818315 1;1818316,2.
