A series of new three-dimensional (3D) lanthanide-transition metal (4f-3d) heterobimetallic open frameworks, [Ln{sub 2}(1,2-bdc){sub 2}(H{sub 2}O){sub 2} Cu(inic){sub 2}](ClO{sub 4}) (Ln=Eu (1), Tb (2), Nd (3) and Sm (4); 1,2-bdc=1,2-benzenedicarboxylate; Hinic=isonicotinic acid) have been hydrothermally synthesized and characterized by elemental analysis, IR, TG and single-crystal X-ray diffraction analysis. Compounds 1-4 are isostructural. They possess a new anion-templated 3D heterobimetallic open framework, which is observed for the first time in the {l_brace}Ln/TM/bdc/inic{r_brace} (TM=transition metal) system. Compounds 1 and 2 exhibit the characteristic fluorescent properties of Eu(III) and Tb(III), respectively. - Graphical abstract: A series of new anion-templated 3D heterobimetallic open framework based on the lanthanide-carboxylate layers and copper(I)-inic pillars, [Ln{sub 2}(1,2-bdc){sub 2}(H{sub 2}O){sub 2}Cu(inic){sub 2}](ClO{sub 4}) (Ln=Eu (1), Tb (2), Nd (3) and Sm (4); 1,2-bdc=1,2-benzenedicarboxylate; Hinic=isonicotinic acid), have been hydrothermally synthesized and structurally characterized, among which compounds 1 and 2 exhibit good fluorescent properties.
