| Abstract: | Two novel lanthanide-organic polymersEr_2(pdc)_2(o-bdc)(H_2O)_2]·H_2O(1,H_2pdc=2,6-pyridinedicarboxylic acid,o-H_2bD_c=1,2-benzenedicarboxylic acid)and Er(Himdc)(mbdc)_(0.5)(H_2O)(2,H_3imD_c=4,5-imidazoledicarboxylic acid,m-H_2bD_c=1,3-benzenedicarboxylic acid)have been synthesized and characterized by elemental analysis,IR,thermogravimetric analysis and X-ray single-crystal diffraction studies.1 crystallizes in monoclinic,space group P2_1/c,while 2 in the orthorhombic space group Pbcn.Both compounds 1 and 2 display two-dimensional network structures.For 1,the tetranuclear parallelogram{Er_4}cluster as a building block is further assembled into a wonderful 2D grid,and the layers are interconnected via hydrogen bonds and π-π stacking interactions to yield a 3D supramolecular architecture;for 2,its configuration is a rare double-decker structure.These two complexes represent good examples for using mixcarboxylate-containing ligands to construct diverse 2D lanthanide coordination polymers. |
