Polynuclear metal clusters, particularly those with aesthetically appealing structures, are of increasing interest. In this study, by employing C4 symmetrical macrocyclic silsesquioxane ligand, a novel tridecanuclear Gd(III) cluster (Gd13) with a {Gd13O8} 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 −ΔSM value of 20 J kg−1 K−1 at 2 K and ΔH = 7.0 T. |
