While the coordination chemistry of monometallic complexes and the surface characteristics of larger metal particles are well understood, preparations of molecular metallic nanoclusters remain a great challenge. Discrete planar metal clusters constitute nanoscale snapshots of cluster growth but are especially rare owing to the strong preference for three‐dimensional structures and rapid aggregation or decomposition. A simple ligand‐exchange procedure has led to the formation of a novel heteroleptic Mn₆ nanocluster that crystallized in an unprecedented flat‐chair topology and exhibited unique magnetic and catalytic properties. Magnetic susceptibility studies documented strong electronic communication between the manganese ions. Reductive activation of the molecular Mn₆ cluster enabled catalytic hydrogenations of alkenes, alkynes, and imines.

锰纳米片：新的簇拓扑和催化

虽然单金属配合物的配位化学和较大金属颗粒的表面特征已被充分了解，但分子金属纳米团簇的制备仍然是一个巨大的挑战。离散的平面金属簇构成簇生长的纳米级快照，但由于对三维结构和快速聚集或分解的强烈偏好而特别罕见。一个简单的配体交换过程导致了一种新型杂配Mn ₆纳米团簇的形成，该纳米团簇以前所未有的平椅拓扑结晶，并表现出独特的磁性和催化性能。磁化率研究记录了锰离子之间强烈的电子通讯。_{Mn 6}分子簇的还原活化能够实现烯烃、炔烃和亚胺的催化氢化。
