Heterodinuclear Cu−Tb Single-Molecule Magnet

A strictly heterodinuclear Cu−Tb complex [LCu(O2COMe)Tb(thd)2]
made with a Schiff base L, thd, and monomethylcarbonate ligands
[L2- = N,N‘-2,2-dimethylpropylenedi(3-methoxysalicylideneiminato);
thd = tetramethylheptanedionato] behaves like a single-molecule
magnet. The monomethylcarbonate ligand, which appears during
the reaction pathway, bridges the Cu and Tb ions.

由Schiff碱L、thd和单甲基碳酸酯配体构成的严格异核Cu-Tb配合物[LCu(O2COMe)Tb(thd)2]，其结构中L2- = N,N‘-2,2-二甲基丙二烯双(3-甲氧基水杨酰亚胺亚氨基)[thd = 四甲基庚二酸酯]，展现出单分子磁体的特性。在反应过程中出现的单甲基碳酸酯配体，起到连接Cu和Tb离子的桥梁作用。
