Based on the magnetocaloric effect (MCE), cryogenic magnetic cooling is one of the most promising applications of molecule-based magnets. In recent years, 4f-clusters played important roles and set up several records in such area, some of which exhibit large and promising cryogenic MCE catching up the commercial coolant GGG. Here in this chapter, we focus on the structure–magnetocaloric correlations of 4f-clusters and 4f-cluster-based coordination polymers for use as cryogenic magnetic coolants. The assembly strategies are introduced and discussed on the purpose of obtaining high performance 4f-clusters for cryogenic magnetic cooling. Then, the recent development is summarized and accompanied by the discussion on representative examples. Finally, the outlooks about the future research directions in this area are made.
