A series of dinuclear lanthanide complexes incorporating the 2-ethoxycinnamate ligand have been synthesized and characterized using elemental analyses, infra-red spectroscopy, X-ray diffraction and magnetic measurements. Depending on the nature of the lanthanide ion, three different isostructural series of respective formulas, [Ln(L)3(DMSO)(H2O)]2 (Ln = Ce (1), Nd (2)), [Ln(L)3(DMSO)x(DMF)y(H2O)]2 (Ln = Gd (3), Dy (5) and Er (6)) and [Tb(L)3(DMF)(H2O)]2 (4) have been obtained. Investigations of their magnetic properties reveal a genuine single-molecule magnet behaviour observed for the dysprosium based compound 5, while a field-induced slow relaxation of the magnetization is found for compounds 1, 2 and 3.
一系列包含 2-乙氧基肉桂酸配体的双核镧系元素配合物已经通过元素分析、红外光谱、X 射线衍射和磁性测量进行了合成和表征。根据镧系元素离子的性质，得到了三种不同的同构系列的相应化学式：[Ln(L)3(DMSO)(H2O)]2（Ln = Ce（1），Nd（2）），[Ln(L)3(DMSO)x(DMF)y(H2O)]2（Ln = Gd（3），Dy（5）和 Er（6））和[Tb(L)3(DMF)(H2O)]2（4）。对其磁性的研究表明，基于镝的化合物 5 表现出真正的单分子磁体行为，而化合物 1、2 和 3 则发现磁场诱导的磁化缓慢弛豫。
