| Abstract: | Three novel d10 metal coordination polymers, {[Cd(H2odpa)(phen)2]·H2O}n (1), [Cd2(odpa)(phen)(H2O)2]n (2), {[Zn4(odpa)2(phen)2(H2O)2]·H2O}n (3), (H4odpa = 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 cross-linked by (odpa)4− anions. In 1-3, central CdII/ZnII 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. |
