Syntheses, structures and luminescent properties of lanthanide coordination polymers assembled from imidazophenanthroline derivative and oxalate ligands

Nine new lanthanide coordination polymers have been synthesized under hydrothermal conditions. Compounds 1-7 exhibit a 3D tfz-d network. Compounds 8-9 display a 1D chain structure. The structural variation from compounds 1-7 to 8-9 can attribute to the pH effect on construction of lanthanide coordination polymers.213
