Lantern-shaped 3d-4f high-nuclearity clusters with magnetocaloric effect

Two lantern-shaped, high-nuclearity 3d-4f clusters {Ln(52)Ni(52)}(Ln = Gd and Dy) were synthesized by using iminodiacetic acid (H(2)IDA) and isonicotinic acid (HIN) as the co-ligand under solvothermal conditions. Magnetic studies show a large magnetocaloric effect (MCE) for the gadolinium analogue.

在溶剂热条件下，以亚氨基二乙酸（H₂IDA）和异烟酸（HIN）作为共配体合成了两个灯笼状的高核3d - 4f簇合物{Ln₅₂Ni₅₂}（Ln = Gd和Dy）。磁性研究表明，钆类似物具有较大的磁热效应（MCE）。
