The controlled assembly of well-defined planar nanoclusters from molecular precursors is synthetically challenging and often plagued by the predominant formation of 3D-structures and nanoparticles. Herein, we report planar iron hydride nanoclusters from reactions of main group element hydrides with iron(II) bis(hexamethyldisilazide). The structures and properties of isolated Fe , Fe , and Fe nanoplatelets and calculated intermediates enable an unprecedented insight into the underlying building principle and growth mechanism of iron clusters, metal monolayers, and nanoparticles.
从分子前驱体可控组装定义明确的平面纳米团簇在合成上具有挑战性，并且常常受到三维结构和纳米颗粒的大量形成的困扰。在此，我们报道了主族元素氢化物与双（六甲基二硅氮基）铁（II）反应生成的平面氢化铁纳米团簇。分离出的Fe 、Fe 和Fe 纳米片以及计算得到的中间体的结构和性质，使人们能够以前所未有的方式深入了解铁簇、金属单层和纳米颗粒的潜在构建原理和生长机制。
