In [Mn(5-MeOsalen)(Cl)]2(dibenzo[24]crown-8), dibenzo[24]crown-8 formed a supramolecule via multi-point interactions with the [Mn(5-MeOsalen)(Cl)] dimer. The dimer was magnetically isolated with ST = 4 and weak interdimer magnetic interactions. The crystal exhibited single-molecule magnet behaviour with an anisotropic barrier of 26(1) K, which is the highest among the Mn-salen series reported to date.

解锁单分子磁性:在晶体环境中分离中性 MnIII salen 型二聚体的超分子策略

在[Mn(5-MeOsalen)(Cl)] 2 (二苯并[24]crown-8)中,二苯并[24]crown-8通过与[Mn(5-MeOsalen)(Cl)的多点相互作用形成超分子] 二聚体。二聚体被磁隔离,S T = 4 且二聚体间磁相互作用较弱。该晶体表现出单分子磁体行为,各向异性势垒为 26(1) K,是迄今为止报道的 Mn-salen 系列中最高的。
