Lanthanide-oxo cluster is a kind of multi-nuclearity lanthanide complex formed by connecting multiple lanthanide ions through oxygen bridges.Lanthanide-oxo clusters usually have unique optical,electrical,magnetic and catalytic properties due to the synergistic effects between poly-metals.In recent years,high-nuclearity lanthanide-oxo clusters have become one of the frontier research fields that attract extensive attentions because of their beautiful molecular structures and potential applications.This review outlines the effective synthetic strategies for synthesizing high-nuclearity lanthanide-oxo clusters,ligand-controlled lanthanide hydrolysis method and anion template method,and summaries the rules of building block assembly for high-nuclearity lanthanide-oxo clusters.At the same time,perspectives for future studies on high-nuclearity lanthanide-oxo metal clusters are also discussed.
