Two bidentate pyridine-triazole ligands (3-(pyridine-2-yl)-5-phenyl-1,2,4-triazole (L1) and 5-phenyl- 2-(2'-pyridyl)-7,8-benzo-6,5-dihydro-1,3,6-triazaindolizine (L2)), have been synthesized and used for Ln(Dbm)3 (Ln = Sm(III), Nd(III), Yb(III) and Er(III)) coordination. The structures of the ligands and resulting Sm(III) complex were determined in the solid state by X-ray diffraction. The title complexes were characterized by UV, fluorescent, IR-spectroscopy and thermogravimetric and elemental analy- sis. Photophysical studies on the Ln(III) complexes were carried out showing luminescence in the re- gion typical for Ln(III). The effect of various factors on the enhancement luminescence of complexes are discussed.

Ln(III) complex, 1,2,4-triazole derivatives, X-ray study, luminescence.
