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.
基于罕见的三角双锥 Ln(5) 簇作为节点,构建了两个 3D 异金属有机骨架,并对其结构和磁性进行了表征(Ln=Gd(1),Dy(2))。结果表明,1 中具有高达 30.7 J kg-1 K-1 的大磁热效应,2 中具有缓慢的磁弛豫行为。预期,基于多核簇作为节点构建 3D MOFs 将是实现大 -ΔS(m) 的一种新策略。此外,化合物 1 表现出高的热稳定性和溶剂稳定性,为实际应用提供了有利的基础。
