Molecular isomerization has been well established in small-sized organic molecules, whereas bulk inorganic solids present the phase transformation. Studies of molecular isomerization and phase transformation have thus far proceeded largely independently. Significantly, the nanocluster-based structural isomers occupy the boundary between molecular isomerization and phase transformation—they serve as small-size nanoparticles but display the molecule-like isomerization rather than the bulk-like phase transformation. The subject of structural isomerism has emerged recently as a new “growth point” in the nanocluster science. In this Review, we highlight the advances in researching the structural isomerism of atomically precise nanoclusters. We first discuss the geometric structures of nanocluster structural isomers. Nanocluster quasi-structural isomers are then reviewed. The factors that account for the structural isomerism and the interconversions between nanocluster isomers are disclosed as well. Then, we elaborate on the structure-dependent properties of these nanocluster structural isomers and highlight the ligand effects on structures and properties. Finally, the present challenges in studying the nanocluster structural isomerism, as well as some personal perspectives toward this research direction, are proposed. This review hopefully provides researchers attempting to study the nanocluster structural isomerism with a researching fundamental.

原子精确的纳米簇中的结构异构

分子异构化已在小型有机分子中得到很好的确立，而大量的无机固体则具有相变。迄今为止，分子异构化和相变的研究基本上是独立进行的。值得注意的是，基于纳米团簇的结构异构体占据了分子异构化和相变之间的边界-它们充当小尺寸的纳米粒子，但表现出分子状的异构化而不是本体状的相变。最近，结构异构现象成为纳米簇科学中的一个新“增长点”。在这篇综述中，我们重点介绍了研究原子精确的纳米团簇的结构异构现象的进展。我们首先讨论纳米簇结构异构体的几何结构。然后审查了纳米簇的准结构异构体。还公开了解释结构异构性和纳米簇异构体之间的相互转化的因素。然后，我们详细介绍了这些纳米团簇结构异构体的结构依赖性，并重点介绍了配体对结构和性质的影响。最后，提出了目前研究纳米簇结构异构现象的挑战，以及对这一研究方向的一些个人看法。这篇综述有望为尝试研究纳米团簇结构异构现象的研究人员提供基础研究。我们详细介绍了这些纳米簇结构异构体的结构依赖性，并重点介绍了配体对结构和性能的影响。最后，提出了目前研究纳米簇结构异构现象的挑战，以及对这一研究方向的一些个人看法。这篇综述有望为尝试研究纳米团簇结构异构现象的研究人员提供基础研究。我们详细介绍了这些纳米簇结构异构体的结构依赖性，并重点介绍了配体对结构和性能的影响。最后，提出了目前研究纳米簇结构异构现象的挑战，以及对这一研究方向的一些个人看法。这篇综述有望为尝试研究纳米团簇结构异构现象的研究人员提供基础研究。
