Three Giant Lanthanide Clusters Ln(37) (Ln = Gd, Tb, and Eu) Featuring A Double-Cage Structure
Three homometallic high-nuclearity clusters, formulated as [(CO3)(2)@Ln(37)(LH3)(8)(CH3COO)(21)(CO3)(12)(mu(3)-OH)(41)(mu(2)-H2O)(5)(H2O)(40)]center dot(ClO4)(21)center dot((H)2O)(100) (abbreviated as Ln(37), Ln = Gd (1); Tb (2); Eu (3), LH3 = 1,2,3-cyclohexanetriol) and featuring a double cage-like structure, were obtained through the reaction of 1,2,3-cyclohexanetriol, acetate ligand, and Ln(ClO4)(3). The largest odd-numbered lanthanide cluster Gd37 exhibits an entropy change (-Delta Sm) of 38.7 J kg(-1) K-1.
