摘　　要：Polynuclear metal clusters,particularly those with aesthetically appealing structures,are of increasing interest.In this study,by employing C 4 symmetrical macrocyclic silsesquioxane ligand,a novel tridecanuclear Gd(III)cluster(Gd13)with a{Gd 13 O 8}core featuring unprecedent body-centered Archimedean cuboctahedron conformation is realized using an efficient solvothermal method instead of conventional Schlenk techniques.To the best of our knowledge,Gd13 cluster is thus far the highest nuclearity of lanthanide-silsesquioxane.Moreover,a magnetic study reveals a weak antiferromagnetic interaction between adjacent Gd ions in the cluster.In addition,Gd13 exhibits cryogenic magnetocaloric effects with a maximum−ΔS M value of 20 J kg^(−1) K^(−1) at 2 K andΔH=7.0 T.
