Crystal growths in gel medium of lanthanide-based coordination polymers with 2,5-dihydroxyterephthalate (dhbdc2−) as ligand lead to two different crystal structures depending on the lanthanide ion. Lanthanide-based coordination polymers that crystallize in these two structural type have respective chemical formulas [Ln2(dhbdc)3(H2O)12·6H2O]∞ with Ln = La-Nd, and [Ln2(dhbdc)3(H2O)8·6H2O]∞ with Ln = Sm-Yb plus Y. Only the Nd-based and the Yb-based coordination polymers exhibit luminescence properties in the near-infrared region.
