3 D MOFs containing trigonal bipyramidal Ln5  clusters as nodes: large magnetocaloric effect and slow magnetic relaxation behavior.
Two 3D heterometal-organic frameworks based on infrequent trigonal bipyramidal Ln(5)  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 -ΔS(m). Additionally, compound 1 exhibits high thermal and solvent stabilities, providing a favorable foundation for realistic applications.
