Three polymeric erbium(Ⅲ) complexes [Er(oba)(Hoba)(H 2O) 2]H 2O (A),[Er 2(oba) 3(H 2O) 4] (B), [Er 2(oba) 3(2,2′ bpy) 2] (C) (H 2oba=4,4′ oxybis(benzoic acid), 2,2′ bpy = 2,2′ bipyridine) were hydrothermally synthesized by altering the metal/carboxylate ratios or in the presence of an additional chelate 2,2′ bpy ligand, and characterized by single crystal X ray diffraction. The results show that different metal/carboxylate ratios can influence the polymeric structures and the presence of 2,2′ bpy ligand alters the topology of the framework from two dimensional to three dimensional.
