Abstract

A [Mn18] wheel of wheels is obtained from the reaction of MnBr2·4H2O and LH3 in MeOH. The metallic skeleton reveals two asymmetric [MnIII6MnII2] square wheels connected into a larger wheel via two MnII ions. Magnetic susceptibility and magnetisation data reveal competing exchange interactions, supported by computational studies.

摘要

通过 MnBr2·4H2O 和 LH3 在 MeOH 中的反应得到了一个[Mn18]轮烷。金属骨架显示出两个不对称的[MnIII6MnII2]正方形轮通过两个 MnII 离子连接成一个更大的轮。磁化率和磁化数据表明存在竞争的交换相互作用，这得到了计算研究的支持。
