摘要：
Two 3D heterometalorganic frameworks based on infrequent trigonal bipyramidal Ln5 clusters as nodes were structurally and magnetically characterized (Ln=Gd (1), Dy (2)). The results indicate large MCE of up to 30.7 J?kg-1 K-1 in 1 and slow magnetic relaxation behavior in 2. Expectedly, constructing 3D MOFs based on multinuclear clusters as nodes may will be a new strategy for achieving large -?Sm. Additionally, compound 1 exhibits high thermal and solvent stabilities, providing a favorable foundation for realistic applications.
