摘　　要：以席夫碱配体N,N′-双(3-甲氧基亚水杨基)乙烯-1,2-二胺(H2salen)为原料,合成了2个新的镧系配合物,即[Dy(salen)_2]_3·3C_2H_9N_2·2CH_3OH(1),[Ho(salen)_2]_3·3C_2H_9N_2·1.5CH_3OH(2),并对其进行了基本表征。X射线单晶衍射结果表明,配合物1和2结晶于单斜晶系C2空间群,其金属配位环境类似。配合物1和2在零场和外加磁场下均具有单分子磁体(SMMs)行为。Two new lanthanide complexes based on Schiff base ligand, namely [Dy（salen）2]3·3 C2 H9 N2·2 CH3 OH（1）and [Ho（salen）2]3·3 C2 H9 N2·1.5 CH3 OH（2）,（H2 salen =N,N′-bis（3-methoxysalicylidene）ethylene-1,2-diamine）, have been synthesized and characterized. Single-crystal X-ray diffractions reveal that 1 and 2 crystallize in the same monoclinic space group C2, and have similar coordination environment around the metallic centers. Single molecule magnets（SMMs） behaviors have been observed in 1 and 2 with/without an applied magnetic field.CCDC： 1827419, 1; 1827420, 2.
