Magnetic molecules known as molecular nanomagnets (MNMs) may be the key to ultra-high density data storage. Thus, novel strategies on how to design MNMs are desirable. Here, inspired by the hexagonal structure of the hardest intermetallic magnet SmCo, we have synthesized a nanomagnetic molecule where the central lanthanide (Ln) Er is coordinated solely by three transition metal ions (TM) in a perfectly trigonal planar fashion. This intermetallic molecule [Er(ReCp)] (ErRe) starts a family of molecular nanomagnets (MNM) with unsupported Ln-TM bonds and paves the way towards molecular intermetallics with strong direct magnetic exchange interactions-a promising route towards high-performance single-molecule magnets.
被称为分子纳米磁体（MNMs）的磁性分子可能是超高密度数据存储的关键。因此，需要有关如何设计分子纳米磁体的新策略。在此，受最硬的金属间磁体SmCo的六边形结构启发，我们合成了一种纳米磁性分子，其中中心镧系元素（Ln）Er仅以完美的三角平面方式由三个过渡金属离子（TM）配位。这种金属间分子[Er(ReCp)]（ErRe）开启了一族具有无支撑Ln-TM键的分子纳米磁体（MNM），并为具有强直接磁交换相互作用的分子金属间化合物铺平了道路——这是通往高性能单分子磁体的一条有前途的途径。
