摘要
本文采用氮氧自由基和稀土元素镥(Ⅲ)的六氟乙酰丙酮盐进行自组装,得到了一个金属-自由基配合物,并对其进行了结构和磁性的表征。结构分析表明,该分子由两个氮氧自由基和两个镥(Ⅲ)离子单元构成,变温磁化率的分析表明两个自由基之间存在着较弱的反铁磁相互作用。
In this paper, a metal-radical complex was successfully obtained by self-assembly of nitronyl nitroxide radical and lutetium（Ⅲ） hexafluoroacetylactonate, and its structure and magnetic properties were characterized. The structural analysis shows that the molecule consists of two nitronyl nitroxide radicals and two lutetium（Ⅲ） hexafluoroacetylactonate moieties. The temperature dependence of the magnetic susceptibilities reveals that there exist weak antiferromagnetic interactions between two radicals.
