摘要：

Two novel rare earth coordination polymers, [La(pydc)(2)(H2O)][La(pydc)(H2O)(2)](H2O)-H-. (1) and [Sm(pydc)(2)(H2O)][Sm(pydc)(H2O)(2)](H2O)-H-. (2) (pyde = pyridine-2,6-dicarboxylate) were hydrothermally synthesized and characterized by the elemental analyses, IR spectra and TG analyses. Single crystal X-ray diffractions show that 1 and 2 are isostructural compounds. In the compounds of 1 and 2, the ID lanthanide helical chains are connected each other by lanthanide binuclear dimer as building blocks to form a novel 3D covalent framework. (C) 2004 Elsevier B.V.
