Dinuclear lanthanide(III) metal complexes, [(Hpmide)Er(NO3)2]2 (1), [(Hpmide)Tm(NO3)2]2 (2), and [(Hpmide)Yb(NO3)2]2 (3) have been prepared by the reaction of N-(2-pyridylmethyl)diethanolamine (H2pmide) and metal (M) salts (M = Er(III), Tm(III), and Yb(III)) in methanol. Lanthanide(III) metal complexes were characterized by elemental analysis, IR spectroscopy, single crystal X-ray diffraction, and photoluminescence. All complexes belong to the monoclinic P21/n space group. The metal ions in the dinuclear lanthanum(Ⅲ) complexes show 9-coordinated geometric structures. In the structures, each metal ion is connected to an oxygen atom of the Hpmide- ligand. In the complexes, strong bands at 263 nm are shown due to the pyridine group of the Hpmide- ligand. In addition, each complex was observed unique photoluminescence behaviors in the solid state which is attributed to lanthanide(III) metal ions. In this poster, we will present and discuss the synthesis, structure, and physical properties of new lanthanide(III) dimers 1-3.
