✦ Synopsis

A series of new three-dimensional (3D) lanthanide-transition metal (4f-3d) heterobimetallic open frameworks, [Ln 2 (1,2-bdc) 2 (H 2 O) 2 Cu(inic) 2 ](ClO 4 ) (Ln ¼ Eu (1), Tb (2), Nd (3) and Sm (4); 1,2-bdc ¼ 1,2benzenedicarboxylate; Hinic ¼ 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 {Ln/TM/bdc/inic} (TM ¼ transition metal) system. Compounds 1 and 2 exhibit the characteristic fluorescent properties of Eu(III) and Tb(III), respectively.
