Abstract
- Graphical abstract The synthetic strategy and building block about high-nuclearity lanthanide clusters are summarized, demonstrating the role of template anion in their assembly. Highlights • High-nuclearity lanthanide clusters, because of their unique physical and chemical properties and their potential application, have attracted great much attention in different fields. Owing to the final structures of the lanthanide clusters not only sensitive to starting materials used in the synthesis, but also to reaction conditions including metal ions/ligands ratio, pH, solvents, temperature, duration, rational design and synthesis of lanthanide clusters remains a great challenge. Thus, it is necessary to review the recent advance in the assembly of high-nuclearity lanthanide clusters. • In this review, the synthesis of high-nuclearity lanthanide clusters using the anion template strategy was outlined based on recently reported results. The presence of small anionic species appears to be essential as a template for modular build-up of higher-nuclearity cluster complexes. Compared with a single-anion template, the slow release of anions, multiple anions or mixed anions as templates is more conducive to the assembly of high-nuclearity lanthanide clusters because of their dispersive effect on the positive charges of the clusters. • Based on the structures of the lanthanide clusters recently achieved, the building blocks in the lanthanide clusters were analysed. Some of the high-nuclearity lanthanide clusters with sophisticated structures are assembled from two or more types of structural motifs. Using this building block strategy, abundant clusters featuring multiple combinations of these basic motifs have appeared at a fast rate. • Perspective in future study on the high-nuclearity clusters is discussed. For the rational design and synthesis of lanthanide clusters, future investigations should focus on the assembly mechanism of the lanthanide clusters, which not only being helpful to the rational design and construction of the high-nuclearity lanthanide clusters, but also to the properties study on the high-nuclearity lanthanide clusters. Abstract High-nuclearity lanthanide clusters have attracted much attention in different fields because of their unique physical and chemical properties and their potential applications. In this review, the synthetic strategy and building blocks for the assembly of high-nuclearity lanthanide clusters are outlined based on recently reported high-nuclearity lanthanide clusters. Perspectives for future studies on high-nuclearity lanthanide clusters are also discussed. We hope this review will provide insight into future research on high-nuclearity lanthanide clusters.
