Utilizing quinaldichydroxamic acid (H2quinha), a tetranuclearity YbIII−based complex with the formula [Yb4(Hquinha)8(C2H5OH)2(H2O)6](ClO4)4·4C2H5OH·2H2O (1) was synthesized and characterized. In 1, there are two coordination geometries of YbIII ion, pentagonal bipyramid and trigonal dodecahedron. Magnetic properties of 1 show slow magnetic relaxation, representing the first polynuclear YbIII complex with single−molecule magnet behavior. In addition, complex 1 displays an emission peak at 530 nm originated from organic ligand.

罕见的基于发光Yb（III）的单分子磁体
利用喹啉异羟肟酸（H 2 quinha），一种具有式[Yb 4（Hquinha）8（C 2 H 5 OH）2（H 2 O）6 ]（ClO 4）4 ·4C 2 H的基于四核Yb III的配合物合成并表征了5 OH·2H 2 O（1）。在图1中，Yb III离子有两种配位几何形状，五角双锥和三角十二面体。磁性1显示慢磁弛豫，代表第一个具有单分子磁体行为的多核Yb III配合物。另外，复合物1在530nm处显示出源自有机配体的发射峰。
