N2 - 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(μ 5-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. Synergistic coordination: Two types of synergistic coordination between organic 4-pyridin-4-yl-benzonate and oxalate/acetate ligands, as well as organic 4-pyridin-4-yl-benzonate and inorganic Br/I ligands were simultaneously observed in two series of sandwich frameworks based on linkages of two distinct layered networks of nanosized LnIII and CuI wheels, La18/3Cu@Cu24 in FJ-21 and Ln24/Cu2@Cu24 in FJ-22, by 4-pyridin-4-yl-benzoate ligands (see figure).
