A new family of 2D coordination polymers based on 3d‐4f 15‐metallacrown‐5 (MC) units were designed and characterized. The connection of the 15‐metallacrown‐5 subunits by the coordination of Cu II and ligand led to the formation of 2D network of metallacrowns. Analysis of the magnetic properties of these coordination polymers reveals that the Gd III ( 1 ), Tb III ( 2 ), and Dy III ( 3 ) complexes exhibit slow magnetic relaxation and under 1000 Oe dc field, and the Dy III ( 3 ) complex exhibits single‐molecule magnet behavior.
