Abstract

Three new dinuclear complexes [CuCl(o-van-en)Ln(HO) Cl]Cl·CHO (Ln = Sm (1), Eu (2), Gd (3); H(o-van-en) is the Schiff base formed by 2/1 condensation of o-vanillin and ethylenediamine) were prepared in a single crystal form by the method of horizontal diffusion. The prepared complexes were characterized by chemical analyses and IR spectroscopy. The three complexes are isostructural and the Cu(II) is situated in the smaller cavities while the larger cavities accommodate larger Ln(III) atoms. The pentacoordination of the Cu(II) atoms is completed by a chlorido ligand in the apical position, while the octacoordination of the Ln(III) atoms is achieved by three additional aqua and one chlorido coligands. AC susceptibility studies have shown that complexes 2 and 3 exhibit field supported slow magnetic relaxation while complex 1 does not display AC activity.

摘要

通过水平扩散法制备了三种新型双核配合物[CuCl(o-van-en)Ln(HO)Cl]Cl·CHO（Ln = Sm (1)、Eu (2)、Gd (3)；H(o-van-en)是由邻香草醛与乙二胺以2/1缩合形成的席夫碱）的单晶形式。通过化学分析和红外光谱对所制备的配合物进行了表征。这三种配合物具有同构结构，Cu(II)位于较小的空穴中，而较大的空穴容纳较大的Ln(III)原子。Cu(II)原子的五配位由顶端位置的氯配体完成，而Ln(III)原子的八配位则通过另外三个水和一个氯共配体实现。交流磁化率研究表明，配合物2和3表现出场支持的慢磁弛豫，而配合物1不显示交流活性。
