| Abstract: | Two series of sandwich frameworks, La6(μ3‐OH)2(ox)3L12Cu11(μ3‐X)6(μ2‐X)3]?8 H2O (X=Br/Cl, FJ‐21 a/b ; L=4‐pyridin‐4‐yl‐benzonate; ox=oxalate) and Ln4(OAc)3(H2O)4L9]Cu(μ3‐I)]@Cu10(μ3‐I)(μ4‐I)6(μ5‐I)3]?7H2O (Ln=Pr/Nd/ Sm/Eu, FJ‐22 a / b / c / d ; OAc=acetate) have been hydrothermally prepared. These sandwich frameworks are assembled by two different kinds of nanosized lanthanide(III) and copper(I) wheel cluster units, La18 and 3Cu@Cu24 in FJ‐21 , Ln24 and Cu2@Cu24 in FJ‐22 . The synergistic coordination between organic ligands, L and oxalate/acetate, leads to the formation of La18 and Ln24 wheels, while the synergistic coordination between organic L and inorganic Br/I ligands results in 3Cu@Cu24 and Cu2@Cu24 wheels for FJ‐21 and FJ‐22 , respectively. Thus, two types of synergistic coordination between two different organic ligands, as well as inorganic and organic ligands are simultaneously observed in FJ‐21 and FJ‐22 . |
