Three novel d(10) metal coordination polymers, {[Cd(H(2)odpa)(phen)(2)]center dot H2O}(n) (1), [Cd-2(odpa)(phen)(H2O)(2)](n) (2), {[Zn-4(odpa)(2)(phen)(2)(H2O)(2)]center dot H2O}(n) (3), (H(4)odpa = 4,4'-oxydiphthalic acid, phen = 1,10-phenanthroline) were obtained with different metal/ligand ratios through hydrothermal method and characterized. Compound 1 forms a one dimensional zigzag chain, in which two phen ligands chelate to one cadmium atom. Compound 2 shows a three dimensional network structure comprised of new tetranuclear cadmium clusters as the nodes and (odpa)(4) anions as the linkers, exhibits an unusual topological structure. Compound 3 is an unprecedented three dimensional polymer based on octanuclear zinc clusters crosslinked by (odpa)(4) anions. In 1-3, central Cd-II/Zn-II ions and (odpa)(4) ligand display completely different coordination modes and conformations. In addition, the thermal stabilities and photoluminescence properties of 1-3 were also studied. (C) 2009 Elsevier B. V. All rights reserved.
